Derivation of Osher’s Riemann Solver

Derivation of Osher’s Riemann Solver

All numerical fluxes are functions of the left and right states (and possibly dt and dx). Learn how those famous fluxes can be implemented, or just use them to see how they work for various shock-tube problems. Included are Lax-Friedrichs, Richtmyer, MacCormack, Steger-Warming, Van Leer, AUSM, Zha-Bilgen, Godunov, Osher, Roe, Rusanov, HLL, HLLL, AUFS flux functions.
