A robust parallel delaunay mesh generation approach suitable for three-dimensional TCAD

A new approach for mesh generation has been developed to fulfill the requirements of three-dimensional TCAD with respect to a full utilization of the available upcoming computational power of multi-core CPUs. Parallelization and robustness of the meshing algorithm are facilitated by employing a rigorous surface treatment, which not only enforces prescribed quality criteria such as the Delaunay property, but also allows to decouple the subsequent parallel meshing steps. The presented approach is especially applicable for modern TCAD applications through the combination with the constructive solid geometry method, state of the art programming techniques and programming paradigms.
