I am currently analyzing a mechanism which has a ball screw driven by a motor. I want to model this joint in rigid dynamics module. In APDL MPC184 element is provided for such joint. But which should I choose in mechanical?
Fluent offers different temporal discretization schemes. There are two implicit schemes: Second order and bounded second order. I am wondering what are the advantages and disadvantages of these...
