NACA0012 meshing problem
 

HI friends,
I am new to the gambit. I am trying to mesh NACA0012 with chord length of 2.My farfields are 50C from the airfoil. I have followed the cornell tutorials. Everything goes well except the last part when I am trying to mesh the airfoil face its giving negative area(mesh is going inside the airfoil) and skewness >98.
I am using MAP scheme to mesh the face.
If you want I can send the dbs file.
