Convergence
hi,
I have a question... how can I converge an equation with just a convection term? I don't have any diffusion and unsteady and source terms... does it have any specific discretization? :( 
More detail
Can you describe in more detail what it is that you are trying to do?

In this situation my code is running to diverge.

Is that something like Div (rho*V) =0 ? that is a constraint, must be satisfied coupling it to the other equations.

C is the concentration of species. 
the key is the same, the convergence of the solution is obtained while solving a system of equations, you can not focus only on this single equation

1) u momentum 2) v momentum 3) pressure correction 4) oxygen concentration 5) water concentration in water concentration I just have a convection term as follow: Div ( rho*U*C) = 0.0
