So I was simulating laminar flow in a 2-D wavy channel but I get 0 pressure drop between the translational boundary conditions. I calculated the pressure at the inlet and the outlet and found the difference and divided it by the length but I get meaningless results which I suspect to be incorrect. In addition I computed it alternatively by using the wall shear stress but I get meaningless results too. What should I do?

Does this also mean that my pressure data is invalid? Can I instead calculate the pressure a distance after the inlet and a distance before the outlet to calculate the pressure drop?
