Detailed Description

HLLC capability: the model provides the CONTACT wave speed and the STAR STATE on side k.

• contact_speed(UL, UR, pL, pR, sL, sR, dir) -> s* (intermediate wave speed);
• hllc_star_state(U, p, s, s_star, dir) -> U*_k (star state on side k, s = sL or sR). With pressure + wave_speeds, HLLCFlux then applies the GENERIC algorithm F* = F_k + s_k (U*_k - U_k) without any layout assumption. Both methods must be POPS_HD (called in the kernels).
