Abstract

A method to simulate compressible flows at all speed on unstructured grids is presented. Special effort is set on low Mach number flows both in two and three dimensions. Weakly compressible flows can be treated by applying an asymptotic analysis to the equations. The behaviour of a multigrid method solving the linearized system is shown. Furthermore adaptive grid refinement and parallelization is used.
