Hi John, I agree that one will be severely limited on the choice of the CAD tool since I am looking at it from a designer's & a service provider's point of view. I understand that Rand is planning to release a CAD independent version of Procision - though their release schedules are not clear yet. Did you have a chance to validate your thick walled cylinder problem with another FEA solver. How far off were the results?
