Abstract

This paper outlines a method to obtain high order polynomial geometry representations from triangulated surfaces (STL files). The main application in mind for this procedure are discontinuous Galerkin methods of high order, where the produced data can be used to accurately represent material properties. The presented strategy is implemented in the freely available open source mesh generator Seeder. It makes use of a robust flood-filling of the domain with an arbitrary number of colors to represent different computational areas. Seeder produces a mesh format, that is suitable for processing on large scale parallel systems with distributed memory.
