Hyperbolic brick of a model: flux + wave speed + variables + cons<->prim conversions.

Definition physical_model.hpp:181

Detailed Description

Hyperbolic brick of a model: flux + wave speed + variables + cons<->prim conversions.

Variables, conversions and flux are physically LINKED (a flux is written for a given layout of variables): they form a single brick distinct from the source and the elliptic. conservative_vars() and primitive_vars() are MANDATORY (not an optional extra). No source nor elliptic RHS here: those are other bricks of CompositeModel.
