For our plasma modeling work, we use existing software and codes, like COMSOL Multiphysics, ZDPlasKin and HPEM, but we also write our own codes. For instance, for plasma kinetics modeling, we write internal code to interact with ZDPlasKin and many other coding tools (in Fortran and MATLAB), also beyond plasma kinetics modelling, for reaction analysis, conversion of chemistries between platforms (ZDPlasKin to COMSOL), automatic post-processing of BOLSIG+ data, etc. Also for our computational fluid dynamics modeling, we develop several tools and methodologies for combining various approaches, like self-consistent 3D coupled gas flow – plasma models to solve very complex plasma problems with realistic simulation times.
