Creo 2.0 Simulate - Stuck in optimization

New member
Hi all,
I looked into old threads and I found something about the same issue, but no solution.

I set up a very simple mechanical analysis. It runs fine in a few seconds.
If I set up the same analysis for an optimization study, it gets stuck while trying to open Creo to change the optimized feature.

Checking the model before creating elements...
These checks take into account the fact that AutoGEM will
automatically create elements in volumes with material
properties, on surfaces with shell properties, and on curves
with beam section properties.

Any idea?

Thanks

It's now more than 1.5y ago this thread opend;
Is there a fix?

I'm having the same trouble on 2 PC's.

It keep looking like this:
