Hello Burak,

the current tetra contact algorithm is implemented by myself, but it was a
bit quick work and I am a bit afraid that there are some cases the
algorithm would not work (ar at least not properly). Anyway I think it is
possible to use it at least as a starter.

If you know contact forces and contact points, it is possible to
interpolate these forces to nodes (tetra's vertices). So what you asked
should be possible.

For the FEM like particles, do you plan to use elastic behavior, or also
some more complicated constitutive law? Recently I did some work of the
same kind, but using an external FEM program.. I will put the information
on wiki in a few days time.

cheers
Jan
