STokes model/PDE

Please login with a confirmed email address before reporting spam

hello every body
i'm traying to solve a 2D Navier Stokes model coupled with Darc's flow. I built a rectangular shape and i keyed on the boudaryies on P and u. for the velocity on y, i created a PDE (boudary PDE) to account for Darcy (. But when i put v=Hx (the differential of H) i get an error.
is there any methods to solve this problem differently?
