Dear Rwoolhou, 

I tried with very less Spring Constant (0.0001), yet there was this problem. Bottom -> User defined & Top surface -> Rigid body. 

When I select "Rigid body" for the Top surface, I have to select the same UDF as that for Bottom and it gives me this warning :

Warning: incorrect cg motion UDF scourModel::lib5udf on zone 5 (assuming no motion)

Thank you 

With regards
