update the results of FEM unit tests:
|

|
|
import TestFem
|
|
TestFem.create_test_results()
|
|
|
|
copy result files from your_temp_directory/FEM_unittests/ test directories into the src dirctory
|
|
compare the results with git difftool
|
|
run make
|
|
start FreeCAD and run FEM unit test
|
|
if FEM unit test is fine --> commit new FEM unit test results
|
|
|
|
TODO compare the inp file of the helper with the inp file of FEM unit tests
|
|
TODO the better way: move the result creation inside the TestFem and add some preference to deactivate this because it needs ccx
