Cannot load GUI module in console application

[misterwazlib]

Just to be clear, what I meant is that I would like to get the inp file (for example as attached here) as exported file.

[bernd]

two possibilities:

use the testmode which was implemented for unit tests: The sollowing works for me on FreeCAD 0.17.13005 (you have to have greater than 0.17.12995)

Code: Select all

import FreeCAD
docpath = FreeCAD.ConfigGet("AppHomePath") + "data/examples/FemCalculixCantilever3D.FCStd"
doc = FreeCAD.open(docpath)

for o in doc.Objects:
    print(o.Name)


analysis = doc.Analysis
solver = doc.CalculiX

from femtools import ccxtools
fea = ccxtools.FemToolsCcx(analysis, solver, test_mode=True)
fea.setup_working_dir()
error = fea.check_prerequisites()
fea.set_analysis_type("static")
error = fea.write_inp_file()

or use the solver frame work solver, but this is not yet tested well. See code in unit test how to run this: https://github.com/FreeCAD/FreeCAD/blob ... 1289-L1314

hope it helps bernd

Many thanks for the help Bernd!

This works perfectly, however I still don't knw how to export the generated inp file. When I run your code in the console mode I can't see the inp text anywhere.

I tried to export it with

Code: Select all

import Fem
Fem.export(u"C:/FreeCAD_0.17.13005_x64_dev_win/test.inp")

but I don't see the file test.inp anywhere in the directory

[bernd]

set working with no argument sets the working path to your working path pref. Pass a path if you would like to use a diffetent one. The used working path is returned and printed. Your inp file will be in this path.

post the output off my code if you gone run it.

ah I didn't read the output thoroughly, the inp file is there in the working directory

many thanks again for your help!

anyway you told me to post the output so here it is

if you pass a path with set working dir you can set it to any dir you like

Code: Select all

fea.setup_working_dir('YourOwnSpecialInputFilePath')

Hello everybody,

I've tried to run bernd's test mode script and then got this error message:

Code: Select all

Traceback (most recent call last):              (100.0 %)
  File "test.py", line 14, in <module>
    solver = doc.CalculiX
AttributeError: 'App.Document' object has no attribute 'CalculiX'

How can we solve it? Thanks in advance!
