Detailed Description

template<int dim>
struct DNDS::Euler::Gas::RoePreamble< dim >

Pre-computed Roe-averaged quantities shared by all Riemann solvers.

Holds the Lm/Rm thermodynamic state and the Roe averages derived from them. Computed once by ComputeRoePreamble(), consumed by HLLEPFlux, HLLCFlux, and RoeFlux.
