Summary
An unstructured Finite Element method for the transient solution of the compressible Navier-Stokes equations using triangular respectively tetrahedral elements is presented. For convergence acceleration a Multigrid solution method has been implemented. A Domain Splitting scheme improves the performance of the solver mainly in case of time-dependent flows. An efficient solution method for parallel computations is proposed including two decomposition methods. The automatic mesh generation scheme allows for the application to arbitrarily shaped boundaries. A linear behaviour of the generation time In dependence on the mesh size has been achieved. An adaptive remeshing procedure enables the directional refinement and coarsening. The mesh quality is improved by an adaptive smoothing process.
