Parallel computation of 3-D electromagnetic scattering using finite elements

Parallel Computation of 3-d Electromagnetic Scattering Using Finite Elements

The finite element method (FEM) with local absorbing boundary conditions has been recently applied to compute electromagnetic scattering from large 3-D geometries. In this paper, we present details pertaining to code implementation and optimization. Various types of sparse matrix storage schemes are discussed and their performance is examined in terms of vectorization and net storage requiremen...

Time Domain Electromagnetic Scattering Using Finite Elements and Perfectly Matched Layers

We consider a model for the interrogation of a planar Debye medium by a non-harmonic microwave pulse from an antenna source in free space, and we compute the reflected solution using finite elements in the spatial variables and finite differences in the time variable. Perfectly Matched Layers (PMLs) and an absorbing boundary condition are used to damp waves interacting with artificial boundarie...

Parallel 3-D Electromagnetic Particle code using High Performance Fortran: Parallel TRISTAN

A three-dimensional full electromagnetic particle-in-cell (PIC ) code, TRISTAN (Tridimensional Stanford) code, has been parallelized using High Performance Fortran (HPF) as a RPM (Real Parallel Machine). In the parallelized HPF code, the simulation domain is decomposed in one-dimension, and both the particle and field data located in each domain that we call the sub-domain are distributed on ea...
