Fluent Lift solution

  Dear all,
  
  I am working on a basic 3D blunt wing simulation for a velocity of 60 m/s with C-shaped boundary domain. I have taken K-e Realizable turbulence model with Enhanced wall treatment for the simulation with different AoA of 0, 2, 4 and 6. However, as AoA increases, Lift and drag both should increase until stall. But, in my case the drag is decreasing and the Lift is giving me similar value in the range of 0.2 and 0.3. The lift and drag monitors have been converged but I am in doubt with the mesh. I have attached the mesh pictures here and could you please suggest me the reason behind this? Thanks..!!

  I'd suggest doing this in 2d as it'll run much quicker (unless you're looking at tip effects?). Have a look at the meshes used in the Tutorials and YouTube videos.
