Well done Agnes
Anxious to find out what PTC will report on SPR 2258467. It should not have been possible. Everybody runs the majority of analyses with a default mesh and SPA. This should give decent results, especially in displacements. It is the basis of Creo Simulate that you should not worry about meshing. There is no such thing as a margin of safety in this case. we are investigating out-of-roundness for valves, PTC's answer can not be trusted now. (that's a period I just typed)
We'll wait (hopefully only very short)
