I think the problem is with the collisions between masses and faces.  I
increased the number of masses in the vertical direction and ran a simple
test.  I also decreased the number of time steps by a factor of 10 for the
test and it seems to work just fine.


...

     step_count 500
     time_step (1/30)/500
...

    group {MechSim_Generate_Box(<0,0,0>, 0.025, 100, 200000, 5000, true,
<0.5,1.0/9,0.1>, <2,10,2>, Move, 4)}
