I reached out to ANSYS help, and this was their response after playing around with my file:
"This random selection [this is in reference to the random generation of geometry data created by the statistical setup] may cause that “clean stop” does not work. The process needs to reselect a new group of data if it restarts.
I think it is a limitation and Maxwell does not support this “clean stop” for this optimization method of statistical analysis so far, and we could see the error of “Statistical analysis failed” after clicking “clean stop”.
I could submit a defect to developer and see what they say. It takes time.
I could submit an enhancement request to keep solved data in this optimization method, but do not know if it could be completed in this optimization theory. Thanks."
