I used the SimulationXpress one one part like a few times, and now it just fails everytime I try to use it. It said "failed to mesh" and on the left in the red box it sais "failed faces 0 and failed edges 0" or something like that.
Is SimulationXpress just broken?
It tells me surface mesh successful but volume mesh failed and to reduce element size (which I did all the way down). Help!
