about Roe matrix !
hello all,
I'm now studying the Roe scheme. But I didn't find how to express the flux's jacobi matrix in terms of (density,velocity,enthalpy ).Who may tell me how to get the expression of the matrix? thanks.

Hi,
Equation:U_t + F_x=0 (*) where U=transpose of[rho rhou rhoE] and F=transpose of[rhou rhou**2+p rhouH] * is rewritten as U_t + A U_x=0 where A is the Jacobian matrix A= dF/dU. Differentiate the flux matrix components wrt the components of U. gita
