      Hello All,
       
      I have uploaded two snips case 1 and case 2.,

      In case 1 wing is flat and velocity is at 7deg angle., i.e., cartesian x and z components, lift generated is 248N,

      In case 2 wing is tilted to 7deg, velocity is normal to boundary, Lift generated is 550N,

      I don't know where am making wrong sir., please help me out.

      Lift force is perpendicular to chord. So the first case where wing is flat force on Z axis is lift force. In second case where wing is tilted force on Z axis is not lift.
