I need some help with Pro/Mechanica. I am analyzing a wedge shaped chopper mounting block and I would like to do a Modal analysis using contact regions or free interfaces with a force pressing on the wedge. Since Modal analyses are only calculating the natural frequency of certain geometry, I think that Mechanica assumes everything is rigid. However in this instance I would like to see how the frequency changes with a varying preload, so I do not want Pro/E to assume the assembly is a solid part.
