This happens when I attempt to re run a study on a model that previously caused no problems. SW 2013 win7 pro 64. SW runs normally. No changes to the original model or to the system. If I try and run the ball valve tutorial, I receive a message to the flow is supersonic. If I try and view any of the results, the program doesn't respond and the wait or terminate window pops up.
So, did you try to contact support services? Your SolidWorks vendor should have some kind of tech support for this issue, or at the very least they can point you in the right direction for support.
