A METHOD FOR MULTI-DIMENSIONAL ELECTRODYNAMIC SIMULATIONS ON UNSTRUCTURED MESHES

I. V. Sobolev
VANT. Ser.: Mat. Mod. Fiz. Proc 2019. Вып.4. С. 3-20.

The paper describes numerical simulations of electrodynamic equations on unstructured polyhedral meshes by a second-order Godunov-type method. For ideal magnetohydrodynamics we use three difference schemes based on an approximate Riemann solver. We also discuss exclusion of the numerical magnetic charge by the CT method. The difference scheme for Maxwell’s equations employs an exact Riemann solver. Test simulations are presented and compared with published data.

Keywords: Maxwell’s equations, equations of ideal magnetohydrodynamics, Godunov method, unstructured meshes.
