This paper uses the fictitious boundary method described in [1] for the solution of incompressible flow with moving rigid bodies in complex geometries. The method is based on a special treatment of Dirichlet boundary conditions inside of a FEM approach in the context of a hierarchical multigrid scheme such that the flow can be efficiently computed on a fixed computational mesh while the solid boundaries are allowed to move freely through the given mesh. In this paper, we focus on the… CONTINUE READING
