Abstract
Analysis of lightning electromagnetic field using the FDTD method have been studied in recent year. However, large-scale three-dimensional analysis on real environment have not been considered, because the FDTD method has huge computational cost on large-scale analysis. So we have proposed a three-dimensional moving window FDTD (MW-FDTD) method with parallel computation. Our method use few computational cost than the conventional FDTD method and the original MW-FDTD method. In this paper, we have studied about computation performance of MW-FDTD parallel computation and large-scale three-dimensional analysis of lightning electromagnetic field on a real terrain model using our MW-FDTD with parallel computation.
