[GAMBIT] NACA0012 meshing problem

parvez2683 · June 18, 2009, 23:15

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.

post a picture of your issue, with a zoom in your issue.
If you enable the shade-option, is the interior of the airfoil also shaded?

Hi MAX,
I have attached the zoomed in(shaded) file of my problem.
After Using shade option it shades only the outer part not the inside of the airfoil.

Try to split the outer surface along the x(x<0) axis.
And remesh both surfaces, it should help
