We want to optimize a washer using mechanica. However the Relation "sin(trajpar * 360 *8)*.5" does not have a good way to interface with parameters. Is there jlink or proprogram or otherwise optimize-able way to do this?
I think that the contact surface changes under compression are going to cause some serious problems if you are going to analyze the spring itself. Also the spring will be undergoing 'self contact'. This usually causes major headaches for strictly mechanical (linear FEA code). Think of a bellows collapsing and folding in on itself without violating the boundary of the 3D geometry.
I don't use Mechanica specifically, so I don't know its' non-linear capabilities, but these are the things to watch out for.
