Detailed Description

Roe capability: the model provides its FULL Roe dissipation d = |A_roe(UL, UR)| (UR - UL) – Roe average, wave decomposition, entropy fix included (these are properties of the physical system, not the core).

RoeFlux then becomes F = 1/2 (F_L + F_R) - 1/2 d, without any Euler assumption. POPS_HD required.
