A distributed implementation of the finite difference time‐domain (FDTD) method
International Journal of Numerical Modelling: Electronic Networks, Devices and Fields, 1995AbstractThe finite difference time‐domain (FDTD) method is a well known numerical technique that has been used to solve electromagnetic boundary value problems. However, the method requires large computational resources to solve a problem, restricting its use on sequential computers to small problems.This has led to the use of expensive supercomputers ...

Conformal finite difference time domain (FDTD) with overlapping grids
IEEE Antennas and Propagation Society International Symposium 1992 Digest, 1992A conformal FDTD technique based on overlapping grids is proposed. Sample calculations show that this conformal FDTD is more accurate than the staircasing FDTD and that the bookkeeping seems to be less intensive than that of the locally distorted grid conformal FDTD. The authors have built 2-D and 3-D overlapping grid conformal FDTD codes and have done

Finite-difference time-domain (FDTD) analysis using distributed computing
IEEE Microwave and Guided Wave Letters, 1994This paper describes an implementation of the finite-difference time-domain (FDTD) calculations using PVM [Parallel Virtual Machine] 3.2 and a cluster of workstations for a test problem involving a three-dimensional rectangular cavity. It is found that the speedup factors achieved in FDTD calculations can approach the maximum values for large problem ...

Finite Difference Time Domain (FDTD) Simulations Using Graphics Processors
2007 DoD High Performance Computing Modernization Program Users Group Conference, 2007This paper presents a graphics processor based implementation of the Finite Difference Time Domain (FDTD), which uses a central finite differencing scheme for solving Maxwell's equations for electromagnetics. FDTD simulations can be very computationally expensive and require thousands of CPU hours to solve on traditional general purpose processors ...
