This tutorial demonstrates moving mesh and AMI with a Lagrangian cloud. It is very slow, as interaction lists (required to compute collisions) are not optimised for moving meshes. The simulation time has therefore been made very short, so that it finishes in a reasonable time. The mixer only completes a small fraction of a rotation in this time. This is still sufficient to test tracking and collisions in the presence of AMI and mesh motion. In order to generate a convincing animation, however, the end time must be increased and the simulation run for a number of days.

About OpenFOAM
OpenFOAM is a free, open source computational fluid dynamics (CFD) software package released by the OpenFOAM Foundation. It has a large user base across most areas of engineering and science, from both commercial and academic organisations. OpenFOAM has an extensive range of features to solve anything from complex fluid flows involving chemical reactions, turbulence and heat transfer, to solid dynamics and electromagnetics.
