update the results of FEM unit tests:
import femtest.testfemcommon
femtest.testfemcommon.create_test_results()
copy result files from your_temp_directory/FEM_unittests/ test directories into the src directory
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
