Hi Bill,
Thanks a lot. It worked fine. I'm now trying to modfiy the surface grid
points based on the originial airfoil profile. I call the NurbsMapping
class to create a new surface from the existing vertices (as in the code
I had attached previously). But when I pass this surface as the "initial
surface" to the hyperbolic grid generator, it throws the same
error...Also Is it possible to modify the vertex information from
AirfoilMapping and then update it?
Regards,
Dominic

Hi Dominic,
The attached file contains the main program airfoil.C that shows how
to generate the naca airfoil grid with the hyperbolic grid generator. I
have also attached some new versions of Overture files that you should
use, replacing the ones you have.
regards,
Bill.
