contact mechanics model + eigenfrequency analysis

I'm using comsol 4.3b to calculate the contact resonance frequencies of a semi-sphere pressed on a surface (a 3D model). Basically, I have performed a two steps study. The first one is a stationary study. The top surface of the sphere is subjected to a uniforme load. Contact pairs have been used to model the contact between the two bodies (as explained in the Cylinder Roller Contact tutorial). This first study results in an indentation of the sphere into the surface. The second step consists in an eigenfrequency analysis. I want to calculate the resonance frequencies of the system "surface indented by the sphere".
How can I say to comsol to start the second study from the deformation resulting from the previous study?
Thanks in advance for your help,
Mel
