Thanks a lot for the reply. So I guess it is not possible to do that with general case of two bodies.
Do you think I can use ContactSphere to do that as one of my object in two bodies contact problem is an elastic sphere.

sfepy does not support contacts of several deformable bodies yet and it is a
difficult thing to implement properly.
