Are you really sure you will get _exactly_ force=0 on an existing 
contact? The only way I think is to write fn=0, otherwise it will always 
be 0.0000... If one day, no luck, one existing contact has zero force, 
you will just miss just one contact in the full packing. Really not a 
big deal. I would not worry about that.
