VizGlow
VizGlow is a robust, industrial simulation tool for high-fidelity modeling of non-equilibrium plasma discharges.
As part of the OverViz Simulation Suite, it can be fully coupled with electromagnetic, fluid flow, and kinetic particle models to provide solutions to a wide range of complex multiphysics problems. It has been used to analyze discharges ranging from low pressure plasma reactors at a few mTorr to high pressure streamers at 15atm, all with a single solver. VizGlow is fully parallelized and can be used to perform large, 3D simulations with complex geometries. Its robust solvers and scalability make it ideal for solving real world engineering problems.
