Frequently Asked Questions (FAQ)


How will FEMtools supplement our suite of FEA and test software?

FEMtools is an add-on to standard FEA programs for the purpose of:

  • Easily comparing FEA results to test data
  • Validation and updating (calibration) of the input parameters of the FE model (boundary conditions, joint stiffness, damping,...)
  • Extending your FEA software with pre- and postprocessing tools (e.g. pre-test analysis, force identification, structural design modification, ...) or to integrate your FEA and test software into new design, analysis or test procedures (stochastic analysis, material identification, ...)
  • Programming your own pre- and postprocessing tools

Why do I need a FEA validation and updating tool?

Test-analysis correlation followed by FEA model updating, are essential steps in a process to gain more expertise in FEA, make better use of test data, and in general more awareness about quality assurance in CAE processes.

Can I implement my own methods in FEMtools or customize existing ones?

FEMtools includes a powerful scripting language that can be used to extend the program, customize existing tools, develop data interfaces with in-house FEA or test software, and many more.

Can I continue to use my existing FEA software?

Yes, because FEMtools is an open and flexible software. You can use your existing solver and interface results with the FEMtools database. Updating procedures that use your existing solver require exporting the FEMtools FE database and launching your existing solver with each iteration loop. This can be entirely automated through the use of data interface programs and drivers written in FEMtools Script.

How do the Windows and Linux versions of FEMtools compare?

They are functionally identical. The user interface (GUI) looks the same on every supported platform. All versions are native ports of a common source code, ensuring optimal performance on every supported platform.

Does FEMtools have to run on the same platform as my FEA and test software?

No. ASCII-formatted files can easily be transported through a network and are machine-independent. Binary files are system-dependent but most of the binary file data interfaces in FEMtools auto-sense the binary format. For example, MSC.Nastran binary OUTPUT2 files generated on a 64-bit Linux platform can be directly imported in FEMtools running on a 64-bit Windows PC.
