Fem Workbench

The Fem Workbench offers data structures and commands to work with Fem meshes.



[0.14] The FEM-Module is only available with the Windows-Versions of FreeCAD.

Linux-Versions would need further work for implementation.

The FEM-Module supports linear analysis of isotropic (uniformity in all directions) material.

Mechanical analysis with calculation of resulting stress (v.-Mises) and displacement is supported.

[0.14] The FEM-module supports analysis of single parts (solids). Multi-body analysis is not implemented yet.

Creating or importing meshes/parts
[0.14] Only parts created within the Part Module are suppported. Parts from Part Design-Workbench or imported parts

or simple copies are not yet supported
