win 7 x64, SW Premium.  I cannot get any simulation study to run.  Even if I create a simple block, restrain it at one end and force it at the other (in compression) it meshes ok but throws up "Study Failed" as soon as it starts the study - no explanation.  I have been doing simulation studdies for some considerable time with reasonable success and much more complex than this so I am at a bit of a loss.  My work system, XP x64 will run simulation ok.  Any ideas?
