VizGrain is modeling tool within the OverViz Simulation Suite for rarefied gas flows, macro-particle (e.g. dust) dynamics and hybrid plasma simulations.



  • 1D, 2D (planar / axisymmetric) and 3D problems
  • Multiple particle types (e.g. multiple species)
  • Particle force models: electromagnetic Lorentz force, gravitational force, aerodynamic drag
  • Particle chargeup models
  • Particle-in-cell (PIC) modeling
  • Particle collisions: direct-simulation Monte Carlo (DSMC) approach, Monte Carlo collision (MCC) approach
  • Coupling to VizGlow™ (hybrid plasma simulations, prediction of complex ion energy and angular distribution functions on processing surfaces)
  • Hybrid unstructured mixed mesh formulation
  • Parallel computing
