Abstract

In most cases, CFD-problems to be solved deal with very complex computational domains. In order to generate an accurate solution for the Euler equations in a reasonable computing time, we developed a self-adaptive parallelized Euler Solver with grid generation fully integrated into the computational flow simulation process. A second possibility to limit the computing time beyond parallelization is a multilevel method. The FAS-method is integrated in the solver.

In this paper two prolongation methods which show a better stability behavior are presented. The first method is based on the idea of a special linear combination of the coarse grid corrections. The second prolongation uses the discretization of the partial differential equation to compute a new correction.
