On SW07 and SW09, we always found that if you have the Simulation add-in enabled but no parts open, then open a part, SW will, without fail, crash.
Are you leaving the add-in enabled after you've closed all parts? As this may be the solution to your problem.
Spot on Dave! Sure beats paying a subscription to solve the problem.
Here's what I did:-
Disable simulation on startup.
Check Simulation add in - disabled.
Open part document which previews a von Mises diagram; Model opens.
Enable simulation; Study tabs appear.
Click on study tab; loads and fixtures display so I re run study and von Mises diagram appears.
I rest Dave's case.
Excellent, glad it works!
For what it's worth, the issue has been fixed in SW11 (possibly in SW10, we skip every other version so I've no idea), so we can now all be lazy and leave the add-in permanently enabled!
This crashing problem is happening with SW 2013, I gues the crashing problem still exist.
