I consistently have a problem with Solidworks crashing when I try to edit a pressure load on an assembly that I'm trying to analyze using Simulation.  I don't get any error message indicating what the problem is.  It happened when I tried to analyze an indiviual part as well.  I have a study set up.  All parameters are defined.  I try edit a pressure load to add pressure to new surfaces by right clicking the pressure load and it locks up completely or crashes and closes Solidworks.  Has anyone experienced this?  Any help would be greatly appreciated.
