Abstract: Abstract The here described new technique allows to simulate rigid bodies in the multiphase code Free Surface 3D (FS3D). The scheme is formulated in an Eulerian framework. Multiple rigid bodies may be considered that are identified by a single Volume-of-Fluid (VOF) variable. Collisions between particles are treated with the exact solution of the excentrical, frictionless collision problem of two arbitrarily shaped particles. The phenomena of drafting, kissing and tumbling are identified when two solid spheres interact in a Newtonian fluid. This case provides a basis for a performance analysis on massively parallel architectures.
