Comparison of Two Explicit Time Domain Unstructured Mesh Algorithms for Computational Electromagnetics
An explicit finite element time domain method and a co-volume approach, based upon a generalization of the well-known finite difference time domain scheme of Yee to unstructured meshes, are employed for the solution of Maxwell’s curl equations in the time domain. A stitching method is employed to produce meshes that are suitable for use with a co-volume algorithm. Examples, involving EM wave propagation and scattering, are included and the numerical performance of the two techniques is compared.
