@pluAtAnsys I pushed commits with the initial implementation of the timeline feature here.
I included a simple test script in \development-testing\feat-implement-timeline\feature_testing.py (to be untracked later), and a sample .speos file with a timeline on which to operate.

The implementation is working in a limited test case, with one exception: when the .speos file is read in, I can't figure out how to correctly set the timeline properties using the imported values (I can't find the imported values...); the timeline property appears with the default value of false, even though the simulation result shows it is actually active.

The same issue appears for stop_condition_passes_number, as we discussed.
Maybe because these are job-level properties, they aren't directly read in with the scene during the .speos import.
I'd appreciate your advice.
