Domain Decomposition for the Finite-Element Electrostatic Particle in Cell Code Michelle

The advancement of modern vacuum electronics into millimeter and sub-millimeter wavelengths places a growing demand on sensitivity analysis which in turn plays an increasingly important role in improving production yield. This results in higher computational demand on simulation software, often pushing it into the realm of High Performance Computing (HPC). Domain decomposition provides one means for increasing simulation resolution and/or decreasing simulation execution time by breaking the volumetric mesh into sub-domains (blocks) which can be distributed over memory and multiple processors.
