picFoam: An OpenFOAM based electrostatic Particle-in-Cell solver

picFoam is a fully kinetic electrostatic Particle-in-Cell(PIC) solver, including Monte Carlo Collisions(MCC), for non-equilibrium plasma research in the open-source framework of OpenFOAM. The solver's modular design, based on same principles used OpenFOAM, makes it highly flexible, by allowing user to choose different methods at run time, and extendable, building upon templated classes. implementation PIC method employing finite volume method, allows simulate arbitrary geometries one three dimensions. OpenFOAM's barycentric particle tracking effectively performe charge field weighting from Lagrangian description Eulerian backwards without computational expensive searching algorithm. also includes open general circuit boundary models real devices.
