How to obtain the dynamic stiffness and damping for a hydrodynamic journal bearing?

I am trying to model a hydrodynamic journal bearing using COMSOL and I can get the static performance of the bearing, but I can't find a way to obtain the dynamic performance of this bearing in terms of stiffness coefficient and damping coefficient. Are there any suggestions to deal with this problem?
