hi,there, I have a problem about the upwind or hybrid scheme,I want to extend my code(central difference for all space derivatives) to fluid field including separation,now,I use Adams-bashforth for the convective terms[i.e.,du/dx(t+1)=3/2(du/dx(t))-1/2(du/dx(t-1))],I wonder,if I can use upwind or hybrid scheme for du/dx(t) and du/dx(t-1) to evaluate du/dx(t+1)?here,t is the time step.

thanks

Yes you can. But, why don't you use the conservative form of the equations? I find it easier to upwind the equations written in conservative form, specially for FVM methods.
