Re: FEM Mod error since 0.19.pre

[felixlee868]

Hi

I Just test my freecad. I found the since 0.19.pre (git hash is: 3d227cf7179c00e57f2733f947b4b1b0368d219a ) , The FEM Mod have beed involved some bugs.
After the release (git hush: 3d227cf7179c00e57f2733f947b4b1b0368d219a ) . I found the freecad will crash when I run FEM Module.

I use condo environment on MacOS. I have tested on MacOX 10.13.2 and I got the same result as my run MacOS 11.4.

I think there are some errors after the release. Please check the code for FEM module. and I hope the problems can be fixed soonly.


Best Regards

Felix Lee

I hope the FEM module can run well on python=3.9 environment also.

[bernd]

seams this is conda related. I do not use conda. Thus I moved it to install / compile. Here it might get more viewers.

I do compile from source on Linux and use prebuild binaries for Windows. I do neither have a problem to run FEM.

If there really are FEM related problems than the FEM forum it the place to post.

I hope the FEM module can run well on python=3.9 environment also.

I do not know of any problems so far.

When I use FEM module, I found the gmsh and ccx can't be called by GUI. When I use gmsh create mesh for one object. The FreeCAD crashed. the next line are prompt information

Active analysis found: Analysis
ElementDimension: 3
Group meshing for analysis is set to true in FEM General Preferences. Are you really sure about this? You could run into trouble!
