The Discontinuous Galerkin Spectral Element Method (DGSEM) is a combination of Finite Element Method (FEM) and Finite Volume method. The current implementation is a high-order (spectral) method. The code achieves adaptivity by estimating the error of each element and decide whether to use the solution refinement or grid-coarsen. The code is implemented in a parallel format using both OpenMP and OpenMPI. The adaptivity would cause load imbalance during the computation procedure. The research involves implements a multilevel domain partition tool to evenly spread the elements among the processors and applies load balancing algorithms to speed up the make-span.
