1- yeah but the residuals for the transient case did not go down 1e-03 within each step (specifically continuity), that is what made me doubt that it was going well.n2- i would just like to confirm how to calculate the time step at CFL~1? is it using CFL=U dt/dx? at CF1~1, this means dt = dx/U. but what is the dx to be used here? is it the minimum edge length, minimum characteristic length, or average characteristic length? they largely differ from each other. n
