Numerical Investigations for Stable Calculation of Meshless Time Domain Method: Influence of Node Alignment on Numerical Stability

摘要

The stabilizing calculation of Meshless Time Domain Method (MTDM) is numerically investigated. In addition, the influence of a node alignment on the numerical stability is also investigated. MTDM does not require finite elements or meshes of a geometrical structure as well as other meshless method. In MTDM, only the necessary information is the location of nodes, and the arrangement of the node structure of electric fields and magnetic fields. The purpose of the present study is to develop the numerical code for analyzing electromagnetic phenomena, and the influence of the node alignment on stabilized calculation is investigated.
