Abstract
The present paper is concerned with methods for the generation of meshes of arbitrary element types. A field method is employed, thus meshes are obtained by a mixed discrete-analogue optimization process. With it's origin on the generation of unstructured simplex grids, the extension to hybrid grids requires an additional discrete optimization tool for the choice and conversion of element types. For this purpose a seed and crystallization method is in development and compared to a more classical zonal approach. The paper is related to the work in progress. Major scope of application is the computation of fluids.
