Solid Edge

Solid Edge

No. Solid Edge 2020, v220, moved to the SPLMS Common License Toolkit to be consistent with other SPLMS products. Moving to the CLT platform utilizes a new license daemon and encryption, therefore will not validate prev220 releases.

Categories: CAD, Solid Edge

Yes. During the transition to v220 customers will be allowed to use their current version v219, ST10, and so on in parallel with v220 during the transition. Once v221 releases, the overuse piracy detection will be reinstated.

Categories: CAD, Solid Edge

No. Along with the move to the CLT platform, the Solid Edge Server Dongles will be retired. All Solid Edge floating licenses will be validated against a Composite ID, like the other SPLMS products on the CLT platform.

Categories: CAD, Solid Edge

Yes. If a customer has not registered a Composite ID for their floating licenses on their Sold to before. To register aComposite ID, connect to the License Management site, login with WebKey, Click on the Composite Host ID , enter the Composite ID and Host Name of the computer, and click Submit.

Categories: CAD, Solid Edge

Customers that have not registered their Composite ID will receive a 30 day temporary license to allow sufficient time for them to the registration process.

Categories: CAD, Solid Edge

Download the GetCID.exe from Support or run the GetCID.exe delivered in the Program folder with the installation of v220

Categories: CAD, Solid Edge

The customer has two options, download another 30 day temporary license from License Management, or proceed to the License Management site, login with WebKey, Click on the Composite Host ID , and register their Composite ID and Host Name of the computer.

Categories: CAD, Solid Edge

No. In order to retain the customer self service use of Product Activation to manage their Node Locked seats, their Node Locked products need to remain on a separate Sold to ID.

Categories: CAD, Solid Edge

No. Customers may keep their Solid Edge Server Dongle and or dispose of it themselves if they so desire.

Categories: CAD, Solid Edge

Yes. The same composite registered for NX & Teamcenter will be used to create a single license file for all three products.

Categories: CAD, Solid Edge

The Partner and or Customer needs to contact their CAA (Customer Account Analyst) and ask to have all of their products consolidated onto a single Sold to. The CAA will initiate the process and provide a Request for Change/Certificate of Discontinuance form to be completed so the change can be made.

Categories: CAD, Solid Edge

Yes. But license borrowing will now be managed via FLEXlm using the same method as NX.

Categories: CAD, Solid Edge

After registering the CID on the License Management page, return to the License Management Home Page, select Passwords and License Files, Select the Product & Version, then click Continue and the license will be downloaded. The instructions have been updated.

Categories: CAD, Solid Edge

In order to provide the best experience for the customer, the CID should be captured and provided when ordering floating software. If the CID is not known or available, the order can be submitted and the CID provided later.

Categories: CAD, Solid Edge

The customer has to contact the Partner/CAA and provide the correct CID. The CAA will make the change at no charge as long as the customer is on maintenance. The CAA will request the customer fill out the Server Replacement Form/Certificate of Discontinuance.

Categories: CAD, Solid Edge

By default the GetCID.exe only shows the composite value needed for floating licenses. Because the tool will primary be used for floating software, the default view was limited to the Composite ID to help avoid the confusion displaying all of the values would cause. If you need to obtain the Composite2 ID, you can use the Solid Edge License Utility or use a “ composite2” command line option with the GetCID.exe. You can see all of the command line options for GetCID.exe by running the exe with a ?.

NX CAD

NX CAD

  • Token, or Value Based Licensing allows customers to use a broad set of different products through a system of tokens that are compatible with, and extend, existing licensing options.   The tokens are enabled on top of prerequisite base seat license(s).  They are available on Subscription basis.
  • Customers buy a fixed number of tokens allowing them to use whatever token-enabled product as long as they don’t exceed the combined token count they have purchased.  When the customer exits NX, the token amount is released again, so that people can start-up other software options. 

Categories: CAD, NX CAD
  • “Tokens” are available in sets that are referred to as “Value-Packs”.
  • Token licensing is available in NX 12.0.2 MP14 and for the Continuous Release series NX 1872 and onward.  
  • Note, customers on NX 12 will have to download and install the MP14 service pack.
  •  A customer must have purchased pre-requisite base seat license(s) which include the floating NX Mach 1 license and above or the Automotive bundles. 
  • The following are NOT valid base seats for tokens:
    • Mach Designer
    • Mach Advantage
    • Mach 1 Node Locked
    • Gateway or UG based bundles 
  • Users purchase a package of tokens to include in the token pool, these are sold in value packs of 50 and 100.
  • The first token pack must be 100 after which tokens can be purchased in quantities of 50 or 100
Categories: CAD, NX CAD
  • Tokens are an extremely flexible way to invest in NX.  They dramatically lower the costs and risks associated with new projects (where customers are starting to use NX but do not yet know the quantity of and the add-on tools they really need).  While most companies will see value in this approach, it may be easiest to describe the value to smaller customers who use many types of design tools and companies where multiple teams need different tools at different times.
  • The NX Design Value Packs are only available as subscription, so all the benefits of subscription licensing apply.  Additional benefits include:
    • Extreme simplicity because new customers only need to buy tokens to cover an overall capacity requirement. This is made up of a number of desktop licenses and a quantity of tokens and avoids customers having to make decisions on each individual product option.  Guidance for Sales to help configure token installations is provided at the end of this document.
    • Increased business flexibility because customers can adapt to different development requirements quickly without having to re-invest.   
    • Increased cost savings for customers who will run a wide variety of applications on an occasional basis.  These customers don’t have to consider peak requirements for individual products but can rather model requirements on overall capacity requirements.   Traditional licensing often requires customers to overinvest in individual product licenses, even if 90% of the time there is no real need for the maximum number of licenses.
    • Reductions in internal purchasing paperwork because customers invest in tokens which allow them to use product you use daily and products you only use occasionally (or don’t even know you need yet)
    • Additional risk reduction 
      • Reduces the risk of over-investing in a certain product options while ensuring customers   have the broad range of products at their disposal.   Doing this in a subscription context allows them to flexibly adjust their token count on a yearly basis.
      • A product option might not have been selected during the procurement process, while afterwards that software option might become critical for a specific (urgent) project.
    • Time savings (vs acquisition of technology)
    • Many new software options will be supported by the token system 
    • Maybe the customer does not really know what they will need so wants a way to be able to use many options and confirm they add value before deciding how to buy them

NOTE: while the plan is to deliver new products with tokens customers.  It is important from a rev rec viewpoint to avoid any commitments that new capabilities will automatically become available in the token pool.

Categories: CAD, NX CAD
  • The tokens are packaged into value packs 
    • NX35100 – NX Value Based Licensing 100 pack
    • NX35050 – NX Value Based licensing 50 pack
Categories: CAD, NX CAD

No, the core modeling, drafting and assembly’s functions are part of the Mach products that form the base of the configuration that the token pool is added to.

Categories: CAD, NX CAD
  • No, there are over 50 products in the token pool, but there are some exceptions.  The token pool does not include:
  • Products with royalty 
    • To ensure we do not violate any partner agreements.
  • Programming authoring tools (NX Open Authoring)
    • This prevents the situation where authoring tools are not available to the people designated to use them at our customers because the token pool is exhausted.
Categories: CAD, NX CAD
  • Tokens that have been purchased by a customer become part of a token license pool.  
    • Each application in the token pool consumes a defined number of tokens when in use.
    • Total number of applications, and which specific applications, that can be checked out on top of the Base Application is limited by the number of tokens that the user has available.
    • When the customer exits NX, the token amount is released again, so that people can start-up other software options.
  • Token licensing can be combined and mixed with the traditional feature-based licensing schemes which also continue to exist. As described above third-party products will not be available under the token licensing scheme.
    • A customer must have purchased pre-requisite base seat license(s) on top of which the tokens can be enabled. 
      • Token licensing does NOT require Teamcenter or any other application beyond the basic license referred to here in order to function
    • If this is used with any other licensing, then the licensing system will use “non-token” licenses first before using tokens.  The strategy is always to maintain as many tokens as possible in the available pool
    • Based on the number of tokens purchased, people will be able to activate a number of software options.   
      • The system will allow any token enabled license to be used if there are sufficient tokens available.  
      • When the user exits the application, the tokens are returned to the pool.

The token licensing is based on the same approach taken by the STS team with the Simcenter 3D licensing.  The calculation of token values for the add-on products is the same.

  • This approach has strong benefits for both small deployments requiring broad set of applications or products and for large deployments with many applications / products.
    • The majority of our customers probably fall into the middle where traditional licensing is felt to be best solution.   
  • If a customer has need for a single application like MCD or Mold then it is most likely the most cost effective approach is to sell the specific products.  
  • Looking at each as examples:
    • NX11113 Mechatronics Concept Designer – $35,200 plus $7745 ME&S
  • Using tokens
    • NX11110 Mach 1 Product Design – $16,129 plus $3535 ME&S
    • NX35100 NX Value Based Licensing 100 pack – $16,308 p.a.
  • While year 1 is slightly lower cost, ($43K to $36K) the customer breakeven is approximately 17 months into the contract.
    • NX13200 MoldWizard – $27260 plus $5180 ME&S
  • Using tokens
    • NX11110 Mach 1 Product Design – $16,129 plus $3535 ME&S
    • NX35100 NX Value Based Licensing 100 pack – $16,308 p.a.
    • NX35050 NX Value Based Licensing 50 pack – $8,148 p.a
  • With a base of Mach 1 we do still not have a 100% functionality match, but you can see that the initial cost of the token based approach is more expensive ($32K to $44K)
  • This illustrates the fact that tokens really appeal when there is a need for a wider set of addons.
  • That said, any company looking for new features and capabilities can see the benefit of spending a little more on tokens in order to gain the flexibility of being able to use a much broader product portfolio without further investment.   
    • This would be the case for a customer who has a dedicated pool of licenses but is looking at adding one or two more add-on modules.  
    • Purchasing a token pool on top of the existing licenses is a very cost-effective way of controlling future spend and adding flexibility to the existing capability.  For small deployments start with at least 150 tokens per user, very large deployments with a large number of existing add-ons 50 to 100 tokens per user.

  • In the short term, you can generate revenue by
    • Selling the token pool concept on top of the existing licenses is a very cost-effective way of controlling future spend and adding flexibility to the existing capability Enable customers to leverage new capabilities (available through tokens)
  • This model can improve competitiveness in sales situation as it allows us to offer a wider set of solutions than any of our competitors.  Solving more of their engineering problems with our solutions.
Categories: CAD, NX CAD
  • Tokens are a product on the pricelist (just like any other product) so revenue is counted like any other revenue towards sales compensation
    • Once a customer buys into a token strategy then it is important to maintain regular contact to ensure the tokens are being used and add more to the available token pool
Categories: CAD, NX CAD
  • Tokens should not be discounted. The list price is already considered to be a discounted price because of the flexibility and broad access to capabilities that tokens provide.  
  • The token pool consists of products totaling over $500K which is accessible for an investment of less than 25K per year.
  • Discounting undermines the product pricing structure and makes future quotes problematic.
  • That said, the token licensing products are like other PL products and discounts are subject to standard sales management controls.
Categories: CAD, NX CAD

PMO6 documents the policy for all trade in’s – remember that trade-ins are subject to management approval and any residual value can only be used to support a purchase from the same business segment (i.e. trade-ins for Design products can only be used to purchase other Design products.)  Also, customers do not receive any cash value for trade-in products

Categories: CAD, NX CAD
  • A major advantage of having tokens available is that they help a lot in competitive situations. For example
    • Often a lot of the value in our software, is within the software or niche options.   That’s what gets designers excited about our solution.   
      • Tokens allows us to offer all our solutions without driving up discounts needed to align to customer budgets.
      • Without tokens we would be forced to discount in order to include all those nice exotic options.   Complexity and expense will start customers on the path to alternative vendors and / or large discounts.   
    • With Tokens you are able to offer access to a large pool of add-on products at a very aggressive price
      • When competing with a competitor who does not have tokens, we can force him to make his quote extremely expensive, by broadening the scope of the applications.   
  • Tokens also enable you to differentiate in competitive situations upsell the value of a deal by enabling customers to access a larger set of capabilities for a very modest increase in cost.  As mentioned before access to over $500K of add-on modules for a low annual investment.  
  • It is important to remember we have more value-added add-on modules than our competitors, allowing customers to do more with their NX data, Value Based Licensing opens up a wide range of options from capabilities like Assembly Path Planning for Assembly/Disassembly checking to Molded Part Validation to ensure plastic parts are manufacturable
  • Examples:
    • 1.   A medium size electronics company designing and building small devices that contain a mix of PCBs, complex Sheetmetal and sometimes use stylized plastic enclosures.  They have 10 designers wanting to use NX.
      • This mix would introduce the need for the following capabilities:
        • Core modeling and design
        • Advanced Sheet Metal design (NX Advanced Sheet Metal)
        • Advanced styling and surfacing (NX Realize Shape)
        • Ability to import PCB data (NX PCB Exchange)
        • Ability to check plastic part manufacturability (Molded Part Validation)
      •    This could be packaged together and delivered as
        • 10 x NX10110 – Mach 1 Floating
        • 1 x NX30600 – NX PCB Exchange
      • The mechanical design elements could all be delivered by a pool of tokens.
        • Advanced Sheet Metal – 22 tokens
        • Molded Part Validation – 12 tokens
        • NX Realize Shape – 35 tokens
      • Initially this mix could be met with NX35100 – NX Value Pack 100
      • This assumes that there is not a great deal of concurrency.  However, once a number of users start working on complex sheet metal parts or projects that require styling it is highly likely they will reach the limit to their token pool, so adding a NX35050 would give more flexibility.
    • 2.       Heavy Equipment company needs 10 seats of NX plus capabilities for routing of Hydraulics Pneumatics, fuel, electronic harnesses, cabling
      • Cost of adding single seat of piping and tubing, cabling, and harness licenses is ~$70K US + 15.4K ME&S per year
      • To run the add-on applications concurrently 3 users would cost $210K US plus 45.2K ME&S
      • Tokens provide the same capability and allow for 3 users to run concurrently for $4756 per month (57K per year) 
      • In addition, the customer can leverage Mechatronics Concept Designer, Weld Assistant, Advanced sheet metal, realize shape for geometry, VDA checking, Human modelling and a lot more
    • 3.       Small machinery customer comparing cost of SolidWorks to NX. 
      • They need sheet metal, routing, and translators for Creo and V5, they also see MCD as a clear differentiator but buying everything is thought to be too expensive.
      • Tokens provide all of this capability, plus much more for $3397 per month
      • Tokens provide all of this capability and enable you to set up a price /functionality discussion
    • 4.      A customer who doesn’t really know what balance of the add on modules they need in terms of quantities and would like to have some insurance that they can change their mind or use new capabilities they have not thought of so far.
      •  Tokens are an attractive option to this customer because of the flexibility they offer, you are not locking them down to either specific quantities or individual add-on modules.  This can help you avoid situations where users are looking for loan or trial licenses to help them decide on the balance and mix.
  • We will include other compelling examples as the roll out of token licensing continues.  There are opportunities in many industries including automotive suppliers, Mold tool and die shops, and machinery companies.  Please send your ideas in so we can publicize your successes.

  • Moderate to high discounts can dramatically reduce the size of a deal.  
    • Tokens should be positioned as a way for customers to get access to capability for a fraction of the list price.  You should cut the number of tokens before you cut the price
    • Tokens are a way for customers to rationalize license investments.  They already represent substantial discounts over more traditional licensing approaches.     
  • Customers using tokens, have access to a lot of new technology and might start asking questions related this broader set of applications.  
    • An increased focus on training and support is required.  
    • Sell training to maximize the value your customer will get from their investment and stay in contact with them to ensure they are successful.  
    • Our presales team need to understand and be able to show the wide variety of products in the NX Design token pool.  
    • Our support team have an internal process to connect experts who can support customers when they lack local experience of advanced or niche solutions
  • Sales will grow their business by selling more tokens.  So, while new software modules will be developed and can be made available under a token model… This will NOT automatically create new business, even if a lot of customers start using them.   
    • It is important to invest in the customer so that they can successfully use more capabilities which will lead them to reaching the limit of their token-pool and help you sell more tokens.

  • Yes, the token usage will get recorded in the log file. 
  • So, each time a license feature is checked out or checked back in, it will show in the FlexLM log file
Categories: CAD, NX CAD
  • There is an approach to do this using the options file.  A customer can define a quantity of tokens that are always available to a particular group.
  • This is provided by the licensing system and works for NX and Simcenter 3D although it is not technically a “certified” solution we have tested it and it can be implemented.

Tokens can be used this way if they are sold using the GLOBAL PRICE rather than the local list price.

  • Some High-Level Guidelines for Sizing Token Licensing Systems
    • Token pools are most cost-effective when there is a wide variety of NX applications needing to be run.  If four or more different applications are needed—say Routing Electrical, Assembly Path Planning, Human Modeling and STEP AP242—then tokens can be a cost-effective alternative to traditional per-seat licensing.
  • Remember, there is a price uplift on tokens versus equivalent per-seat licenses, so tokens are not always the best way to go.  Consider proposing “mixed” licenses—part tokens, part per-seat—to give the customer the most flexibility at a good price.  NX products that are just over a token “threshold” might be better purchased on a per-seat basis.  Consider Mechatronics Concept Designer for NX (NX30535), which by itself requires 85 tokens.  With the token count and with 100 tokens needing to be purchased (or, 85 tokens consumed from a larger token pool), it might very well be best if NX30535 is purchased on a per-seat basis as the token pool would rapidly become used.  We recommend you run several scenarios—all per-seat, all tokens, and multiple “mixed” ones—to come up with the best proposal for your customer.
  • Consider “daily use” NX products versus “occasional use” NX products.  Assuming the customer is making maximum use of his “daily use” products, tokens can be a very cost-effective approach for proposing multiple “occasional use” products.  Tokens can also be useful for “flex times” when usage spikes upward for a short period of time; tokens enable the spike to be handled and, in the interim, provide “occasional use” flexibility.
  • Customers will ask about trading in their existing per-seat licenses for tokens.  Given the 25% price uplift for tokens, plus the fact that they do not get 100% credit for what they already purchased, a “like-for-like” swap is not in the customer’s financial interest, unless the traded-in products are not being used.  We recommend that you position tokens as being additive to the customer’s current environment

Simcenter 3D

Simcenter 3D

Simcenter 3D Motion software is an integrated, associative CAE tool that provides comprehensive mechanism modeling and analysis capabilities. You can use Motion to simulate and evaluate mechanical systems.

Categories: CAE, Simcenter 3D
  • A motion body represents a rigid body in the mechanism that moves. When you create a motion body, you specify the geometry that defines that motion body. A motion body can be:
    • An assembly component (recommended)
    • A set of solid bodies, curves, points, and so on.
Categories: CAE, Simcenter 3D
  • Joints represent connections between motion bodies.
  • Without any constraints, motion bodies in a mechanism “float” in space with six degrees of freedom (DOF):
    • Three degrees of translation (the X, Y, and Z directions) 
    • Three degrees of rotation (about the X, Y, and Z axes)
Categories: CAE, Simcenter 3D

Support Center->NX->Documentation-> NX series-> Simcenter 3D motion

Categories: CAE, Simcenter 3D
  • A joint driver assigns motion to a revolute, slider, or cylindrical joint or a point-on-curve constraint. It can only be a point on a rigid curve. 
  • Motion body drivers are available only with the Simcenter 3D Motion Solver.
  • These types of motion body drivers are available: 
    • None (lets you remove an existing driver from a motion body)
    • Polynomial 
    • Harmonic 
    • Function 
    • Control 
    • Profile

Motion Workflow

You might not have to perform all of these steps, depending on your situation.

StepDescription
1. Create a motion simulation.You can create a standalone motion simulation or one that references a master part.
2. Set your preferences and environment options.Preferences and environment options are saved in your Simulation file.
3. Create links.For each mechanical feature in your model that moves, define a link.
When you define a link, you can specify parameters such as mass properties, inertia, and initial translation and rotation velocities.
You can also define flexible links, which may be useful when your analysis conditions include sharp impacts or sudden changes in motion, or if the component is flexible enough to affect the motion of the mechanism.
4. Assign materials.If necessary, assign materials to the bodies in your mechanism. Mass density is a key factor in the mass and inertia calculations used in a dynamic motion analysis. If you do not assign a material, the software assigns a default density value of 0.2829 lbs/in3 or 7.83*10–6 kg/mm3.
5. Create joints and other constraints.Joints constrain the motion between two links. You can also create other motion objects such as gear couplers and cables to further refine the motion between links.
6. Define loads and contact.If necessary, define forces, torques, springs, dampers, bushings, and contact.
7. Add a motion driver.A motion driver assigns motion to a link or a revolute, slider, or cylindrical joint. You can define a driver when you create a joint, or you can create a standalone driver that you can associate with a link or joint for a particular solution.
8. Create motion events.If necessary, create motion events to perform such tasks as detecting whether clearances between objects are violated, or measuring the distance between two points or objects.
9. Create a solution.Each solution can reflect different conditions for solving the mechanism.
10. Solve the mechanism.Solve the mechanism to generate results for analysis.
11. Perform analysis tasks.You can animate or articulate the mechanism, populate a spreadsheet with data from the results, create graphs, create a motion envelope, or perform other analysis tasks.
Categories: CAE, Simcenter 3D

A mechanism consists of geometry or assembly components that move cohesively. Defining a motion mechanism consists of these general steps:

  1. Specifying which components move and which are stationary.
  2. You identify the components that move by creating motion bodies.
  3.  Constraining the motion of the motion bodies, which determines how they move relative to each other.
Categories: CAE, Simcenter 3D
  • Dynamic
  • Static
  • Time and step
  • Articulation – quasi-static or kinematics, interactively driven
  • Spreadsheet – quasi-static or kinematics, driven via a live Excel table
Categories: CAE, Simcenter 3D
  • In Motion, you can add flexibility to a motion body. You can represent the deformation of the motion body either by discretizing the volume using a finite element method or using an analytical calculation based on the beam theory formulation using the spline beam method. 
  • Using the Flexible Body , which lets you either use different solvers and solutions to define the flexible body model in Pre/Post or import a Simulation or results file from an external application.

Using the Automatic Flex, which automates the process of creating a finite element flexible body.

Simcenter Femap

Simcenter Femap

Femap has a built in associativity feature when creating entities. It can be difficult to recognize where the associativity is with a given entity. If the entity needs to absolutely be deleted such as a line, one method to remove the associativity is to use Modify > Associativity and remove the associativity of the nodes or elements from that particular entity. From there, the User can delete the entity using the Delete pulldown.

  • Full OpenGL Hardware Acceleration (Double Buffered).
  • Your graphics card supports OpenGL 4.2.
  • If your graphics card doesn’t support OpenGL 4.2 or later, check with your graphics card vendor to see if there is an updated graphics driver with OpenGL 4.2 support. If your graphics card does support OpenGL 4.2 or later, you can turn on Performance Graphics.
    1. Choose File > Preferences.

FEMAP holds parts of your model and results in memory. To reduce the amount of memory FEMAP uses to do this, choose File > Preferences and click the Database tab. In the Database Performance group, reduce the Database Memory Limit by dragging the slider to the left. This decreases the amount of memory FEMAP uses for holding parts of your model and causes FEMAP to rely more on swapping to the scratch file. Note that this does not control the total amount of memory FEMAP uses, which includes commands, holding data in the data table, and drawing your model.

In FEMAP, choose Tools > Data Table to show the Data Table if it is not showing already. Click the Unlock button to unlock the Data Table and select the entities you want to add. Click the Show/Hide Columns button to change which columns are included. For elements, C1-Cn represent the corner nodes and M1-Mn represent the midside nodes. Out-C1 etc represents the current output at the corresponding corner node. Once you have the data table set up how you want it, you can either click Copy to Clipboard and paste it to an Excel file, or click Save to File to save it to a .csv file.

The best element type depends on the geometric shape of the part, but, typically a part modeled with lower-dimensional elements (1D or 2D) will yield more accurate results and faster processing speeds. With that said, 3D elements are necessary when modeling parts with complex features. In the end, each element type has its advantages and there is not a best type for all situations.

FEMAP has a tool that will measure your mesh based on certain criteria or ratios such as aspect or skew. The tool can be found under the drop down menu Tools > Check > Element Quality.

Groups and layers are very similar functions that are fundamental for having an organized model.  The feature that separates the two methods is that an entity (ie. nodes, elements) can only be in one layer at a time while groups can have overlapping entities. Both tools can be used over the other, and in the end it comes down to personal preference.

The Data Table in FEMAP is used to look at model data in a tabulated format. For nodes and elements, it can show geometric locations, resultant displacements, resultant stresses, and more. It is an easy way to collectively look at the model’s computed data. The Data Table can also be exported to the following file formats: *.txt, *.csv, *.rtf.

  • Some customers have noted that CBUSH spring forces or Grid Point Force Balance data (used for Freebody) was not appearing in FEMAP when the model was run from FEMAP, but the did show up when manually importing the results.
  • The workaround is to manually import the .op2 file (File > Import > Analysis Results). There is no more work being done to add new features to the .f06 file reader, only to the .op2 file reader. Starting with 11.1, the plan is to only use the .f06 file reader when the results destination is set to “1..Print Only”. The .op2 file reader will be used wen Results Destination is set to “3..Print and PostProcess” and you will still get all of the info, warning and error messages along with other stuff from the .f06 file (for instance, modal participation factors) which can’t be found in the .op2 or .xdb file.
  • Up through FEMAP 11.0, if you have the Results Destination set to “0..Default”, “2..PostProcess”, “5..Punch and Postprocess”, or “6..XDB”, FEMAP will read the results data out of the .op2 file (or the .xdb file when “6..XDB” is used). In this situation, all the results will be read. However, if you set the Results Destination to “3..Print and PostProcess”, FEMAP will put the results into both the .f06 files and the .op2 file. When FEMAP does the auto import of results, if it sees results in the .f06 file, it uses that for all results, and never imports results from the .op2 file. The problem happens because the FEMAP .f06 file reader, being older legacy code, does not support some items, including CBUSH forces or Grid Point Force data.

FloEFD

FloEFD

SUMMARY

FloEFD performs the first convergence check upon reaching 1 travel.  The term “travel” is an internal calculation terminology and from a user-standpoint can be imagined as the point of time when beginning from the defined inlet(s) a fluid particle passes the outlet(s) for the first time.

The term “Iterations per 1 travel” is a calculus estimate of how many iterations FloEFD needs to perform to reach this first travel.

DETAILS

Sometimes it could be of interest to manually perform such an estimate.

What is the formula with which the value for the term “Iterations per 1 travel” is calculated by FloEFD?

The number of iterations needed to reach 1 travel is calculated by FloEFD using the formula:

Formula for number of iterations per 1 travel

with (total number of mesh cells) = number of solid cells + number of fluid cells + number of partial cells

SUMMARY

Let us assume you upgraded FloEFD to a new Version (e.g. from Version 15.0 to Version 17.0). Is it possible to move or copy the user-modified Engineering Database (possibly containing many user-defined entries) to this new Version of FloEFD in order to be used and accessed?

There are two ways to achieve this:

Method A: Explicit export and re-import of single items or subnodes of the dedicated *.xml Engineering Database file (this method is preferable if the target database has already been modified as well)

  1. Open the Engineering Database from inside the old version of FloEFD (in this example let us assume Version 15 to be the old version).
  2. Select the item you want export.  This could be either a single item or a subnode.  We will use a Combustible Mixture as example here.

Single Item:

Entire subnode:

3. Save the *.xml file to some location on your hard drive (where you’ll find it).

4. Open the Engineering Database from inside the new version of FloEFD (in this example let us assume Version 17 to be the new version).

5. Open the File Menu and select Import.  Select the *.xml file you exported under step 3 and confirm your choice.

6. The import filter will take care of the kind of database entry and will create a new subfolder in the associated user-defined subnode with the name of the imported *.xml file:

7. If this folder is unwanted, you may move the items from the subfolder by dragging and dropping to the subnode directly and delete the subfolder afterwards.

8. Do not forget to save the changes.

Method B: Moving the database of an old version into a new, fresh and clean installation of a new version:

1. Locate the old database.  It should be located in the ProgramData folder, e.g.: C:\ProgramData\MentorGraphics\FloEFD FE15\CHEMBASEUSER2.XML

2. Simply copy this file to the new version folder, e.g.: C:\ProgramData\MentorGraphics\FloEFD FE17\CHEMBASEUSER2.XML3. Restart FloEFD

3. Restart FloEFD.

SUMMARY

Warning in the calculation window saying A vortex crosses the pressure opening warning.

DETAILS

At a pressure boundary you have some recirculation at the edge of the domain.  This can lead to incorrect results.

During simulations a warning can pop up saying a vortex is crossing a pressure opening, this means, you have some recirculation at the edge of the domain. This can lead to incorrect results.

There are a few ways this can be fixed in FloEFD:

Extend the domain size to calculate all the recirculation properly.  This allows FloEFD to resolve the recirculation region and more accurate results will be seen with the expected flow characteristics:

It may be possible that the mesh is too coarse to capture all the effects of the flow in that region, using a local mesh region will allow just this region to be refined:

There may be some flow and overall physics which show time-dependent effects which can result in the goals oscillating and causing this warning.  In this case, you may try to do a time-dependent analysis to further observe these effects and to obtain direct physical time-dependent results.

It may be that for the geometry and boundary conditions, this behavior is correct and further investigation is required.

SUMMARY

Inactive parts still work in FloEFD

DETAILS

“Inactive” for Solid Edge means lightweight (not suppress), i.e. some information is unloaded from memory for easier work with a model, but “inactive” component is still presented in the model.

Please go to Component Control to clear the check box at the right of the components’ name in the list to disable parts or subassemblies.

SUMMARY

Restarting FloEFD or even the computer does not reset the “Calculating” state.

SUMMARY

The Transient Explorer is a fast way to explore FloEFD’s results on cut plots and surface plots after a transient calculation.

It requires much less time and disk space to be created than a classic animation.

DETAILS

Once the time-dependent option has been specified in the General Settings (or the Wizard), it is possible to activate the Transient Explorer saving in the Calculation Control Options window:

The data to set are:

  1. The start and the periodicity of the saving (this saving can be done at each iteration as it will not require too many resources)
  2. The variables to be saved (only those variables will be available for Transient Explorer at the end of the calculation)

Note that the Transient Explorer CANNOT be activated during the solving in the Calculation Control Options from the Solver Monitor window.

Once the calculation is finished, you can activate the Transient Explorer from the Results section either by right-clicking on Results or from the FloEFD toolbars:

The list of available features will be shortened as some objects like Flow Trajectories cannot be shown using the Transient Explorer.  A slider bar will appear in the Graphical Area and it can be used to navigate through the transient results on the displayed plots:

A movie can be exported from the Animation feature.

SUMMARY

Is there a possibility to save parts/assemblies with their associated project definitions and properties such as material definitions, heat sources, boundary conditions, mesh settings, engineering goals etc. which are attached to single parts or assemblies to a library for later use in another project?

How do I access project settings that have been saved into parts/assemblies in other projects once I’ve inserted such a part/assembly?

How do I add component properties from one model into another, different one?  How do I transfer properties?

DETAILS

  1. Open the part or assembly (which you intend to save in a library location for later use) in FloEFD.
  2. Create one or more FloEFD project(s) on this part or assembly.  This does not need to be meaningful geometry. Exception: If you are dealing with complete assemblies, the parts should be aligned properly.  The number of projects depends on the number of “property sets”: for each set there’s one project.
  3. Assign all required properties/boundary conditions to all parts/assemblies in the project or all projects, respectively.
  4. Save all.
  5. Now you can move or copy the parts and assemblies (with the attached FloEFD project properties) as you like on your hard drive for later use.
  6. Now, when you are in a new FloEFD project (e.g. let us assume you now opened a new model and created a new FloEFD project for it), you can insert the existing parts or assemblies (saved under step 5).
  7. Right-click on the Project tree and choose Customize Tree to activate and make the corresponding functionality From Components visible in the pre-processing section of the FloEFD tree.
  8. Activate “From Components”
  9. The item “From Components” appears in the project tree. Right-click on it and select “Add from Components”.

10. A new pane appears at the bottom showing all parts and assemblies for which FloEFD project properties have been detected:

11. Select the FloEFD project from which you want to import the properties from the list of projects:

A green checkmark marks the success of the operation:

12. Then click on the “Add” icon located in the top-left corner of the pane.  All properties will now be added to the new main FloEFD project:

Please note that also some default properties made in General Settings are imported into the “From Components” subtree.

The customer still needs to download the standalone version of FloEFD. Confirm that there is a license attached to the Mentor Graphics license management software: Mentor Graphics has a separate LMTools acting. Download the software through the Siemens or Mentor Graphics website.

Categories: CFD, FloEFD

Use the “Software License Change Notification” document and fill it out with customer information so Mentor can issue a new license to the customer. This assumes that the customer bought the FloEFD license through the Mentor Graphics site (or vendor) instead of through Siemens. If the license was bought through Siemens, use the Siemens license process.
