Abstract: A parallel structured mesh generation method is proposed for FDTD (Finite Difference Time Domain) simulation in this paper by MPI (Message Passing Interface) implementation. This parallel method is based on serial projection and ray tracing. It completely implements the process from surface triangles recorded in a STL (STereoLithography) file to solid hexahedral grids. Furthermore, the parallel method realizes the balanced task allocation for processes which provides almost linear parallelism. Experimental results show that the running time of the MPI program increases in a nearly linear way. As the number of processes increases, the efficiency of the parallel program consistently remains above 80%. [ABSTRACT FROM AUTHOR]
