A new comment on the computation of non-conservative products using Roe-type path conservative schemes

We are interested in the numerical approximation of the discontinuous solutions of non conservative hyperbolic systems. We more precisely consider a non conservative formulation of the usual gas dynamics equations and show how to slightly modify the so-called Roe-type path-conservative schemes to properly capture the underlying shock discontinuities. Numerical evidences are proposed. The present note follows a first comment on the computation of non conservative products in [1].
