PREMISE: I believe I have found a bug. If my model has a material assigned to it, then I run the SimulationXpress Wizard, I get an error saying that the material I have chosen needs a Young's Modulus and a Poisson's ratio.
BUG?: But my material has a Young's Modulus and a Poisson's ratio!
FIX? : If I remove the part's material before running the Wizard and assign the material only when asked. No problems.
