... that's Computational Fluid Dynamics.  I'm specifically interested 
in running a Navier-Stokes simulation using something like the Volume 
of Fluid model to deal with free surface movement.  My first goal is 
to be able to duplicate something like the following simulation of a 
breaking wave:

I want to be able to run similar simulations for waves breaking 
against different shaped walls.

Most people use big programs in C or Fortran (!), and half the 
trouble is learning how to use them, since there's no prayer of 
changing them. However the basic equations can be written in half a 
page, and I don't need it to run very fast.

It could be fun but so far it looks like it will be simpler to build 
a wave tank :-(.

Thanks for any useful pointers.
