what shall I do after get F(i+1/2) in Roe scheme?
 
hi,all I have get the numerical flux f(i+1/2,j,k) of the Roe scheme. How should I do to get the solution of densityand pressure? (I havn't found a whole procedure example to solve n-s equations in Roe scheme.There is no such reference by hands.) May anyone show me such a procedure? thanks

if you solve the n-s equations in FVM,you can get the conservative variables by solving the semo-discrete time related Equations. then you can get the density and pressure from the conservative variables .of course in Roe's scheme,you must find the matrix to get the flux,refer to CFL3D'S user mannual 5.0.get it onlines you can try
