Abstract
One of the most challenging aspects of computational electromagnetics is the visualization of results and intermediates. Especially in cases where the full wave field in a large-scale domain is of interest for further analysis, IO becomes the main limiting factor on parallelism and simulation speed. In order to alleviate this bottleneck, we propose the application of in-situ visualization on large datasets by instrumenting the simulation code with an interface to a general purpose visualization software. In this paper we present a framework providing fields on structured grids for the fast implementation of large-scale FDTD solvers with implicit message passing (MPI) parallelism and included visualization instrumentation.
