  11. Momentum balance in u direction • Only consider advection of velocity component in the local grid direction

  12. Continuity equation • Multiply continuity equation with u

  13. Subtract continuity eq. times u from momentum equation and divide by V

  14. Procedure • Go around the cell centered at u-point • Compute q across cell boundary by averaging qx resp. qy • If q is inward • Compute Qin by multiplying with dnzrespdsc • Compute uin as • Add Qin (uin–u) to advection
