Allowing Interference Meshing in Frequency Analysis.

I am doing an FEA simulation of a Ball in Cone application.  I am able to mesh and analyze in a Static analysis by creating a slight interference between the parts to estimate the contact region between the ball and cone.  In the Connections properties, I select for Global Contact "No Penetration" and this seems to be the selection that allows the mesh to run, with interference, and results in what looks like a reasonable Static Analysis.  The Problem is that "No Penetration" is NOT an option in the Global Contact menu in the Frequency Analysis study type.  Therefore, I cannot analyze the same model having contact region interference to do a frequency analysis.  Can anyone suggest how to best handle a desired interference in the Frequency Analysis?  Thanks.
