A comparative study between structured and unstructured applications of the flux-filter scheme
- Universitaet Stuttgart (Germany)
In this contribution we present our experiences concerning different grid types and algorithms with regard to the mesh quality and the influence on the results of a two-dimensional Euler solver, the so-called Flux-Filter Scheme. Examinations were done for structured and unstructured grids. In case of the unstructured grids, the following algorithms have been tested: Delaunay (Point insertion strategy is center of gravity). Advancing Front Method for triangular and quadrilateral elements. Conversion Method triangles => quadrilaterals (Rank), The Flux-Filter Scheme is a multidimensional upwind scheme similar to the Flux-Fluctuation methods. The solver is capable of treating triangular and quadrilateral elements which facilitates a comparison of different grid types.
