Summary
We discuss a multithread Lepp-bisection algorithm for the refinement of quality tetrahedral meshes over multicore architectures. We include an empirical study that show that an efficient and robust serial implementation was obtained, and that an scalable and efficient multithread implementation was obtained. Furthermore, the algorithms tend to improve the refined meshes.
