VizSpark is a simulation tool within the OverViz Simulation Suite for large-scale multi-dimensional thermal (arc) plasma modeling.


  • 1-D, 2-D (planar/axisymmetric) and 3-D problems
  • Local Thermodynamic Equilibrium (LTE) with special treatment of non-LTE at boundaries
  • Automatic generation of plasma properties
  • Coupling to electromagnetics (arc induced fields and external fields)
  • Coupling to incompressible and compressible fluid-flow (natural convection, shocks, etc.)
  • Conjugate heat transfer with arc+solid domains
  • Material ablation models
  • Moving body dynamics with arc domain
  • Parallel computing


  • Free-burning arcs
  • Wall-stabilized arcs
  • Ablation controlled arcs
  • Arcs in imposed and self-induced flows
  • Magnetized arcs
  • Arcs with electrode erosion

Industries Served:

  • Lighting manufacturers (HID, arc lamps)
  • Heavy manufacturing (welding, cutting)
  • Coating (powder spray coating, etc.)
  • Electrical device manufacturers (e.g. circuit breakers)
  • Automotive ignition manufacturers (spark plugs,etc.)
  • Space propulsion (Arcjets, MPD, etc.)
