In the following thesis, the problem of the numerical flow simulation around moving bodies is tackled. The flow solution concerns incompressible one or two phase fluids without surface tension in the interface. These types of flows are largely applied to marine and oceanographic applications and as a consequence, there has been a need for a robust handling of the grid movement due to wall translation and rotation. Moreover, due to the storage intensity of large sized grids and the massive computational load needed from the computer to perform the required floating point operations, the following work is implemented in parallel computer-architectures. The implementation is conducted via the unstructured parallel CFD code provided by the laboratory coupled with an overset grid assembly library. (EN)
