But there still seems to be a problem with the energy, the particles are
'vibrating' quite a lot in the end.  I suppose this is a general problem
of particle based simulations since they somehow behave like molecules and
this is exactly what the single molecules are doing in a liquid.

That's the advantage of doing things in SDL or as a Povray-patch.  You
have access to the internal intersection routines.
