How to get the result of the FEM analysis ?(I spend the calculation without Gui)

[anastassia]

Code: Select all

docpath = FreeCAD.ConfigGet("AppHomePath") + "data/examples/itogZ.FCStd"
doc = FreeCAD.open(docpath)
Importing project files......
for o in doc.Objects:
      print(o.Name)
SBORKA1228
Analysis
CalculiXccxTools
FEMMeshNetgen
ConstraintSelfWeight
SolidMaterial
FemConstraintInitialTemperature
FemConstraintPressure
FemConstraintDisplacement
FemConstraintDisplacement001
FemConstraintDisplacement002
FemConstraintDisplacement003
FemConstraintDisplacement004
FemConstraintTemperature

analysis = doc.Analysis
solver = doc.CalculiXccxTools
from femtools import ccxtools
fea = ccxtools.FemToolsCcx(analysis, solver, test_mode=True)
error = fea.check_prerequisites()
fea.update_objects()
fea.check_prerequisites()
fea.reset_all()
fea.update_objects()
fea.run()

Running CalculiX ccx......
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "C:\Program Files\FreeCAD 0.17\Mod\Fem\femtools\ccxtools.py", line 684, in run
    ret_code = self.start_ccx()
  File "C:\Program Files\FreeCAD 0.17\Mod\Fem\femtools\ccxtools.py", line 648, in start_ccx
    p = subprocess.Popen([self.ccx_binary, "-i ", f.baseName()],
AttributeError: 'FemToolsCcx' object has no attribute 'ccx_binary'

File .inp with geometry recorded, but the result of the calculation of thermomechanical analysis is not

From the error message, I see that calculix (the solver) could not be launched. I have no clue why, sorry, maybe FEM people come in and help.
Please post your FreeCAD info, as described here: https://forum.freecadweb.org/viewtopic.php?f=3&t=2264 It's likely really important with this particular problem.


And please put your script in [code][/code] tags for viewing pleasure

+1 I changed the post in this regard.

You should put in your FreeCAD info.

As DeepSoic stated, it seams Calculix binary is not found. Are you able to run the FEM 3D example from Start work bench with FreeCAD Gui?

Performing calculations using FreeCad Gui, I get a .frd file with the results.

Prob. move this to FEM subforum ?

[bernd]

done

[bernd]

would you provide your FreeCAD file or some Python code to reproduce your problem.

[bernd]

best would be if you could show the problem with the FreeCAD FEM 3D example from Start WB.

[bernd]

see https://forum.freecadweb.org/viewtopic.php?f=18&t=29729 it works for me with 3D FEM example from Start WB and latest dev version.
