This is a complete model of a rubber sphere impacting a block of steel at the velocity 100 m/s.
The penalty stiffnesses $(pfac_{rubber}=3 \cdot 10^{12}, pfac_{steel} = 1.68 \cdot 10^{13})$
are calculated automatically based on the bulk modulus of the materials,
the size of the elements and on the magnitude of the intitial velocities.
