Acceleration of Time-Domain Finite-Element Method in electromagnetic analysis with OpenMP

Paralleled Time-Domain Finite-Element Method (TDFEM) is developed based on OpenMP for 2-D electromagnetic scattering analysis in this paper. The matrix-vector multiplication in conjugate gradient (CG) solver is parallelized with OpenMP. As a result, the efficiency of TDFEM algorithm is accelerated dramatically with multi-processor PC. The bistatic radar cross sections (RCSs) of some typical 2-D objects are computed with paralleled TDFEM. High speedup ratio and high parallel efficiency are obtained, which provides a practical and effective acceleration method for TDFEM analysis on multi-CPU computers.
