USimHS is a unique computational fluid dynamics code used for applications involving fluid flows at high Mach numbers. With USimHS, users can accurately simulate multi-species and multi-temperature fluid dynamics in hypersonic plasma regimes.

USimHS can be used for the design of spacecraft shielding for atmospheric re-entry, or combined with USimHEDP to study radio communications devices at hypersonic speeds or arc plasma torches. As one of the only commercial tools available for modeling high-Mach flows, USimHS is the trusted solution for hypersonic fluid dynamics.
