[ODE] Approximate Hydrodynamic Forces

[Ander Taylor]

Hi All,

I want to be able to get the speed that each face of a cube, say, is moving 
along its own normal.  So I can apply an opposing force to each face 
dependent on its area.  Is there an easy way to get this info?

I am hoping to approximate hydrodynamic forces, so I can evolve a swimming 
animat.

Cheers,

Ander
