FETD (finite-element time-domain) Analog simulation method based on parallel algorithm

Abstract

The invention discloses an FETD (finite-element time-domain) analog simulation method based on a parallel algorithm and belongs to the field of computational electromagnetics. According to the method, loop iteration solving of an equation is achieved by replacing conventional serial computation by parallel computation based on existing algorithms; in the parallel solving process, a matrix is introduced to convert an equation set in order to overcome dependent relationship of three adjacent moment unknown quantities in a time marching equation, so that paralleling is made feasible. The method enables the problem of low loop iteration solving efficiency of a time marching equation in FETD to be solved at the premise of ensuring computation precision.

technical field

[0001] The invention belongs to the field of computational electromagnetics, and in particular relates to an FETD simulation method based on a parallel algorithm. Background technique

[0002] Since Maxwell's equations were proposed in 1864, people's research on electromagnetic waves has continued to deepen, and the application of electromagnetic theory has spread to other scientific fields such as life science, medicine, material science, and information science. For complex electromagnetic problems, the experimental method is often limited by the high cost of the test and the long research period, and even the experiment cannot be realized. In the theoretical analysis, due to the complexity of the theoretical model, there is a large gap in the analytical solution of classical electromagnetics. Limitations can't even be achieved at all. In order to solve this kind of electromagnetic problems, with the development of computer software and hardware calculatio...
