Numerical simulation of 2D electrodynamic problems with unstructured triangular meshes

We present a generalization of standard Yee approach for Cauchy problem in electrodynamic simulations on unstructured triangulated mesh. In the paper the whole flow from mesh creation to actual simulation is presented. The proposed computation flow is parallel ready and can be implemented for distributed systems (computation servers, GPU-s, etc.). We studied the influence of non-regular triangulation on stability and dispersion properties of numerical solution.
