I'm not certain if this is actually an error or not, so wanted to ask. I know that multiple thermal and multiple stress studies can be run simultaneously, all the while a seperate model can be worked on in SW modeling. I have a stress model that imports thermal study results, but when that study runs it 'whites out' and freezes Solidworks, rendering it useless until the simulation finishes. Is this normal? I'm just confused why they run fine independently, but together they lock it up. It's been a HUGE pain lately when I have 20+ hour simulations, even though I try to run the bulk overnight.
