[ODE] Rigid Body moving to fast, passing through tri-mesh when should collide

We have made a golf game, and sometimes the ball will pass through the 
trimesh completely without detecting collision.  This generally happens when 
the ball is up against a wall, and we shoot at the wall with full power.  It 
sometimes happens when we chip the ball from a higher plane to a lower 
plane.  In both instances the speed at which the ball is moving is very 
fast.  If we lower the amount of force applied when hitting the ball the 
problem is solved, but we would like to know if there is a way we can adjust 
the timestep or set the CFM or ERP to help with this problem.  FYI, Our 
current timestep is 0.005 (called n amount of times based on the elapsed 
time) and we are using ODE 0.039.  We would appreciate any suggestions.
