A discontinuous Galerkin method for the full two-fluid plasma model. (English) Zbl 1196.76039
Summary: A discontinuous Galerkin method for the full two-fluid plasma model is described. The plasma model includes complete electron and ion fluids, which allows charge separation, separate electron and ion temperatures and velocities. Complete Maxwell’s equations are used including displacement current. The algorithm is validated by benchmarking against existing plasma algorithms on the GEM Challenge magnetic reconnection problem. The algorithm can be easily extended to three dimensions, higher order accuracy, general geometries and parallel platforms.
