[SOLVED] - Problems when loading calculix frd file

[EkaitzEsteban]

Hello,

I have some problems when loading an .frd file in FreeCAD.

I create a simple frequency simulation (free-free conditions). The mesh is done by netgen algorithm using first order tetrahedron elements (C3D4).

In report view I check the following error:

Code: Select all

Traceback (most recent call last):
  File "C:\Program Files\FreeCAD 0.17\Mod\Fem\femguiobjects\_ViewProviderFemSolverCalculix.py", line 231, in calculixFinished
    fea.load_results()
  File "C:\Program Files\FreeCAD 0.17\Mod\Fem\femtools\ccxtools.py", line 771, in load_results
    self.load_results_ccxfrd()
  File "C:\Program Files\FreeCAD 0.17\Mod\Fem\femtools\ccxtools.py", line 782, in load_results_ccxfrd
    importCcxFrdResults.importFrd(frd_result_file, self.analysis, result_name_prefix)
  File "C:\Program Files\FreeCAD 0.17\Mod\Fem\feminout\importCcxFrdResults.py", line 94, in importFrd
    step_time = result_set['time']
KeyError: 'time'

KeyError: 'time' ??

I guess that FreeCAD is unable to read the calculix output because this one is different???

I attach the FreeCAD file.

best regards,
Ekaitz.

is outdated and no longer supported.

Your file runs for me on ...

But I would recomend to give 0.19 dev versions a try as long as there are no big merges. There have been no big merges so far. Means lots of small improvements and bug fixes already.

Thank you bernd!

BTW, interesting geometry. What is this used for?

Hello Bernd,

I am using a simple nonsymmetric tetraedron mesh for understanding all calculix outputs in *.dat and *.frd files when performing frequency analyses.

I am also analizing and modifiying the meshing (elements and nodes) using linear algebra.

best regards,
Ekaitz.
