Ok. I was maybe too categoric but I had the feeling by reading your mail 
that it was only damping which let you obtain an equilibrium solution 
(which would be not possible physically without damping). It seems I 
misunderstood.
So the best is what Vaclav adviced : set both bodies as non-dynamic. You 
will then control directly all the features (relative displacement and 
consequently forces) of the interaction.
