shammath::FluidStateSpec Concept Reference

An equation of state paired with the flux/wave-speed operations a Riemann solver needs, so that solvers (see riemann_rusanov.hpp, riemann_hll.hpp) can be written once and instantiated for any fluid state satisfying this interface. More...

Detailed Description

An equation of state paired with the flux/wave-speed operations a Riemann solver needs, so that solvers (see riemann_rusanov.hpp, riemann_hll.hpp) can be written once and instantiated for any fluid state satisfying this interface.
