While doing a NX Co-Simulation, I encountered a problem, that the dynamic result was not the same as the one I got from a "normal" Dynamic/Kinematic simulation.
My procedure was that I just excited my system with a sine wave with Simulink and increased the frequency (amplitude was the same). But against my assumptions, the reaction forces didn't increase. So I decided to do the same simulation with the NX integrated Dynamcs/Kinematics tool. There the forces rised, because of the higher acceleration from the higher frequency.
Had someone else a similiar problem or am I doing something wrong?
