摘要：

There have recently been analyses of lightning electromagnetic fields using the FDTD method. However, large-scale three-dimensional analyses of a real environment have not been considered, because the FDTD method has a huge computational cost in large-scale analysis. Thus, we have proposed a three-dimensional moving window FDTD (MW-FDTD) method with parallel computation. Our method has a lower computational cost than the conventional FDTD method and the original MW-FDTD method. In this paper, we study the computational performance of MW-FDTD parallel computation and large-scale three-dimensional analysis of lightning electromagnetic fields on a real terrain model using our MW-FDTD with parallel computation.
