The Multicomponent Thermodynamic And Transport properties for Ionized gases in C++ (Mutation++) library is designed to provided efficient algorithms for the computation of various properties important in the fields of hypersonics and combustion Computational Fluid Dynamics (CFD) including:

  • Thermodynamic properties
  • Multicomponent transport properties
  • Finite rate chemistry in thermal nonequilibrium
  • A highly robust multiphase equilibrium solver


All reference documentation, as well as installation and usage information for the library and its associated tools can be found here or by clicking on the Documentation tab at the top.
