VizSpark™ is a robust, industrial simulation tool for high-fidelity modeling of thermal (arc) plasmas. As part of the OverViz Simulation Suite, it can be fully coupled with electromagnetic and fluid flow models to provide solutions to a wide range of complex multiphysics problems. VizSpark™ 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.


  • 1D, 2D (planar / axisymmetric) and 3D 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 and solid domains
  • Material ablation models
  • Moving body dynamics
  • Parallel computing
