Accelerating the simulation of Finite Difference Time Domain (FDTD) with GPU
2021 IEEE International Joint EMC/SI/PI and EMC Europe Symposium, 2021In this paper, we discuss the implementation of three dimensional FDTD method to Nvidia’s CUDA architecture. Finite-difference time-domain is a numerical analysis technique used for modeling computational electrodynamics. Since it is a time-domain method, FDTD solutions can cover a wide frequency range with a single simulation run, and treat nonlinear ...

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 ...

Conformal finite-different time-domain (FDTD) with overlapping grids
IEEE Transactions on Antennas and Propagation, 1992It is shown how to use many overlapping conformal grids in the neighborhood of the scatterer while using a rectangular grid away from the scatterer for solving Maxwell's equations. The locally conformal grids allow better approximation of the boundary condition on the scattering object while the rectangular grid preserves the simplicity and accuracy of

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) 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 ...

Ferrite analysis using the finite‐difference time‐domain (FDTD) method
Microwave and Optical Technology Letters, 1992AbstractThis article introduces a new method for analyzing ferrite structures. This method is implemented in a FDTD algorithm; then the computation is directly made in the time domain. An application in the particular case of a two‐dimensional problem is presented.
