I have to admit that I am not entirely sure how to make a”unit test”

if you only would like to run the pricipal stress unit test just do a

Code: Select all

./bin/FreeCAD --run-test "femtest.testresult.TestResult.test_stress_principal"
I usually combine with make ...

Code: Select all

make -j4 && ./bin/FreeCAD --run-test "femtest.testresult.TestResult.test_stress_principal"
Just play a bit. If you have question do not hesitate ...

1) Maybe we should try square x-section rather than round. The shape doesn't matter too much. It's just a way to introduce an internal load.

2) We could try mixed meshes once it can handle embedding 1D or 2D elements in 3D. It would be ideal to model the cable as a string of 1D elements. Or even a 2 D strip would be a great simplification.
+1 and +1
@bernd will there be any further development of the mixed mesh capability?
