We point out a set of generalized state equations requiring the full exceptionality of the M.F.D. system for a one-dimensional flow. Precisely we find that the functions must satisfy a second order parabolic equation; so we are able to determine a set of solutions expressed by means of two arbitrary functions depending on the Riemann invariant .
In a previous paper, considering a one dimensional M.F.D. flow with a generalized equation of state, a set of functions has been determined which makes the system completely exceptional. In this paper we show that the same set of functions also makes the system strictly exceptional. In the last part we determine the evolution of the characteristic shock.
We characterize a set of second order hyperbolic conservative equations that are both compatible with a supplementary conservation law and completely exceptional.
