Abstract
This research aims at developing innovative and ecient strategies to run computational fluid dynamics simulations when large displacements of moving bodies are taken into account. The goal consists of developing new tools to follow the movement of a rigid body in a given three dimensional domain during the simulation, regardless of the displacement and the rotation amplitudes. In this paper the strategies concerning the mesh generation and update are described. This research is conducted within a collaboration between the Fluids-Machines Laboratory of the University of Mons and NUMECA International.
