FEM FrontISTR Workbench
- Set up an analysis model by FEM module (in the same way as calculiX).
- Switch to the workbench FrontISTR and create a FrontISTR solver object by clicking on the toolbar button .
- Open the task panel of SolverFISTRTools and set working directory.
- Click "Write input file"
- Click "Run FrontISTR"
- Check FISTR_Results for post processing.
- static analysis, element check
- geometrical linear|nonlinear analysis
- elements: 1st/2nd order tetrahedron
- loads: mechanical concentrated and distributed loads, gravity
- boundary: points fixed or displacement
- step control: auto time increment and cutback
- linear equation solver
- preconditioner: AMG, SSOR, Diagonal, ILU(k)(k=0,1,2)
- method: CG, BiCGSTAB, GMRES, GPBiCG
- direct: MUMPS
- output file format: AVS, VTK(paraview required)
Features to be supported in the future
- analysis: thermal transfer, dynamic, eigen, frequency
- materials(mechanical): elastoplastic, hyper elastic, creep, visco elastic
- elements: prism, hexa, beam, shell, truss etc.
- FISTR_Results only contains results for surfaces. If you need the interior results, change Output File Format to VTK and visualize the results with paraview.
FEM_FrontISTR can easily be installed via the FreeCAD Addon Manager from the Tools → Addon manager menu. FEM_FrontISTR is under active development and will get new features frequently. Therefore you should update it regularly using also the menu Tools → Addon manager. The FEM_FrontISTR code is hosted and developed on GitHub.
- FreeCAD v0.19+
- Paraview (optional)
