This research aims at developing innovative and efficient strategies to run computational fluid dynamics simulations when large displacements of geometry are taken into account. The goal is to be able to follow the movement of a rigid body in a given three dimensional domain during the simulation, regardless of the displacement amplitude. In these notes the strategies concerning the mesh generation and update are described. This research is carried out within a collaboration between the Fluids-Machines Department of University of Mons and NUMECA International.
