Abstract

In this paper, scalable solver for time domain electromagnetic simulations will be stdudied. This solver is developed with discontinuous Galerkin (DG) method on unstructured mesh. High-order nodal basis, employing multivariate Lagrange polynomials defined on the triangles has been used to expand the electromagnetic fields. Both periodic and perfect electric conduct (PEC) conditions have been implemented. Domain decomposition has been used for the parallelization, and good scalability has been achieved due to the DG algorithm. Benchmarks for this solver on different supercomputers will be shown. At last, large simulations with 1024 processors will be shown.
