how to create 2d unstrucutred airfoil mesh

aero student · March 24, 2013, 12:42

Hello,
I am new to ANSYS CFD, I am hoping to get some guidance on how I can create an unstrucuted 2d grid around an airfoil

What I have done so far

1)imported naca airfoil geometry
2) created far field- c-mesh

now I understand unstructured grids require surface to be created..I assignmed a fluid surface to my farfield, but the problem is my mesh (tri-grid) run through my airfoil, how do I fix this?

I really appreciate your assistance.

Hi
you can use the "Gambit" software for grid generation. There is a helpful procedure for C-type mesh generation around the NACA0012 airfoil in the Gambit's tutorial. you just follow it.
