Currently, we are working to develop a Finite-Element code for granular particle in an incompressible Navier-Stokes Fluid. Here is a page with movies produced by my students.


Here is a page with movies produced by my coworker Jian Chen. Our polyhedral simulation is now working, and I hope we can write the papers of how to do it very soon.

Here is a page with movies produced by my coworker Alexander Schinner. It is more or less a mirror of his old homepage at the University of Magdeburg, but I have added some more extensive explanations.  The granular simulations were performed using polygonal particles and the forcelaw I proposed in Granular Matter 1, p. 83-91which includes static friction, exclusive-volume interaction and damping in normal direction. Similar simulations were performed for the papers 20, 24, 25 and 28 on my  publication list.

Here is another page with movies, produced by my coworker Hiroshi Watanabe. We have been collaborating on the simulation of elliptic particles using the algorithm from paper 26 of my publication list.  He is interested more in thermodynamic systems (conserved energy), I am using it for the simulation of granular materials (with damping and friction). The simulations of elliptic particles has been used in paper 31 on my publication list.
