Re: FEM Result Export to File

I will not help much with the gui, but I tried to update the example: https://github.com/FreeCAD/FreeCAD/blob/master/src/Mod/Fem/femmesh/femmesh2mesh.py#L37-L44 since it gives error on from femexamples.manager import * doc = run_ccx_cantileverfaceload() With FreeCAD 0.20.1 no error is with: from fem...

Re: FEM Result Export to File

I'm looking for the mesh object with deformation scale = 100 not 1. OK. I think it would be nice to add a scale as a parameter, but for now, you can do it manually: 1) Copy the source code to the FreeCAD python console https://github.com/FreeCAD/FreeCAD/blob/master/src/Mod/Fem/femmesh/femmesh2mesh....

Re: FEM Result Export to File

@thschrader @whoneyc According to the description on the wiki, this tool can export the deformed mesh but only for solid elements . For shell elements, undeformed mesh is exported. But maybe it wouldn’t be very difficult to add a code that could handle this. OK. But what must I do? Workflow? Thanks...

Re: FEM Roundup - Looking at the FreeCAD FEM ecosystem to see what features can be upstreamed

I would consider merging fcFEM created by @HarryvL and beso code for topology optimization developed by @fandaL. Instead of merging the existing beso code, it would be much better (regarding further development) to rewrite topology optimization and connect it internally with some solver*. Hopefully...

When you click on the solver object, property view gives you plenty of options for Calculix (both ccx solver objects should support same options), including analysis type.

Re: Thermomech analysis: split inp writing = true stopps ccx

The input is split to few files and Calculix searches for: "FEMMeshGmsh_constraintstemperaturenodesets.inp" but this file written by FC contains spaces in the name: "FEMMeshGmsh_constraints temperature node sets.inp" When I deleted spaces manually, ccx runs well. Tested on OS: Ub...

Re: releasing FreeCAD 0.20.1

Is the bugfix release only for bug fixes or does it include also update of translations?

Re: Documentation of FEM workbench for v0.20

I have just updated initial cantilever example https://wiki.freecadweb.org/FEM_CalculiX_Cantilever_3D

Purge command does not work on the Result object which is saved in this example. One need to delete it and recalculate it to be able to use Purge feature.

Re: Quad Mesh

Recently I am trying to generate quad8 mesh in FreeCAD (ideally via Gui). Is there any way to do it? Try the parameters as suggested by Bernd above (red elipses), but use "Second Order Linear = True" Otherwise, GMSH makes second order quads with 9 nodes (one is in the middle of the elemen...

Re: Topology optimization

Hi, one way is to look how to make it available in Addon Manager and improve current algorithm which becomes messy due to other (experimental) features which are not much used. Just a question, if you (or others) use beso: 1) Do you modify config file manually or use only features which are availabl...
