Abstract
An efficient solution procedure, simulating the interaction between plane electromagnetic waves and electrically large obstacles, is presented. The solution of Maxwell’s curl equations is sought in the time domain by explicit timestepping. The spatial domain is discretised into a mesh of linear tetrahedral elements. To enhance the efficiency of the resulting computational procedure, an edge based representation of the mesh is employed. The Maxwell equations are spatially discretised using a Galerkin method, with stabilisation achieved by the adoption of a Lax-Wendroff numerical flux function. Approaches enabling the accurate modelling of electromagnetic scattering effects over a wide frequency range are investigated, highlighting the significance of the treatment of the mass matrix within the formulation presented. The development of a parallel environment, incorporating parallel mesh generation and parallel solution procedures is also discussed.
