The timestep determination doesn not really matter here. It should be
fixed manually to identical values in both codes, then if only one
explodes there is a problem.

Christian, in order to double check contacts parameters, looking at
input values is not enough. The best way is to simulate a compression on
two spheres and see the displacement/force response. That way, you will
know if the contact behavior is really the same.
