TestFFDCAD.test_ffd_step_pipe_mod_through_files

[ndem0]

Describe the bug
The test_ffd_step_pipe_mod_through_files fails because extra information depending on the running machine are stored in the test file, making extremely difficult to use these kind of test in CI.

To Reproduce
python -m pytest tests/test_ffdcad.py
