Hello, 

did you adjust your time step size accordingly when changing the frequency? 

Also, mesh preview will deform the mesh, hence you will need to re-read the case to a previous state with undeformed mesh. To a Mesh Check and make sure the CG coordinates are valid before you initialize the motion.
