An Efficient Numerical Method for Time Domain Computational Electromagnetic Simulation

2018

In this paper an efficient numerical method in approximating the electric and magnetic fields is provided. The method is based on an implicit leapfrog arrangement in time and without mesh in space. Moreover, a projection scheme is introduced in order to improve the accuracy of the proposed approach and applied into the computational electromagnetic (CEM) framework. The PDEs governing the process are solved and some numerical results are reported to validate the numerical process.

Some numerical modelings beyond the mesh

2015

In recent years meshless methods have gained much attention in several application areas of science. These methods benefit of savings due to the elimination of meshing process and are suite to handle changes in the geometry of the domain of interest. Further advantages come from the ease of implementation, which makes computer codes very flexible. We present some numerical experiences lying in the meshless framework dealing with domain and boundary-type methods.
