Abstract :
In this paper, we present a new matrix-free time-domain method that does not require a matrix solution in nature and is independent of the element shape. The method is applicable to both structured discretizations and unstructured meshes without any need for change. Numerical simulations of both 2- and 3-D examples discretized into irregular elements have validated the proposed matrix-free method and its generality.
