Opens but crashes on all runs.
I just sent an email to my sales representative experiencing the same. I have not seen much traffic on this topic. It seems as if it is just you and me. I am rolling back to 2025.1 to find out if the analysis crashes on that version. So far, I am bringing in a STP with 3 child pieces and using simple weld connection running a modal analysis to verify if it is stable. So far, it does not matter what I run, after it achieves the first physics pass, the simsolid window disappears.
