meshing problem in gambit: geometric tolerance
 

hi all
i am facing trouble in mesh generation around a 2D airfoil. i followed the tutorial of cornell confluence. in order to reduce Y+ i increased the SR and want to increase the number of node points. but as i try to mesh the face, gambit shows 'mesh size is smaller than the geometric tolerance' ... how to solve this problem ??
actually i need around 80,000 elements, while confluence tutorial gives around 10,000. But i can't.

can anyone help me plz.
