Abstract

This work demonstrates how the graphical user interface of VSim (electromagnetic simulation software package) is modified and utilized to run a custom finite difference time domain algorithm. Commercial programs typically offer conventional FDTD functionality. More often than not, researchers may want to use their own code versions with proprietary modelling tools and extensions; for example, high-order differencing or specialized absorbing boundary conditions. VSim offers the flexibility of integrating an independent FDTD solver-engine that is tailored for the end user’s needs. A detailed example is presented here of the replacement of VSim’s own FDTD engine with a high-order FDTD code written with CUDA Fortran. Other custom FDTD codes could be integrated using the presented procedure.
