O-grid mesh for NACA airfoil
5 Attachment(s)
Hej
I am Sathya and this is my first post.. I am trying to do simulations for NACA airfoil for a surface roughness study. I have been generating hexa mesh in ICEM. I am new to Block Meshing. I did C-grid mesh by following Simon tutorials. But since i have to maintain y+ of 30 near the wall to BL calculations , I need to have 0.0001 for my first layer distance which degrades the orthogonal quality when smoothing. i attached pics of that. So I switched for O grid block mesh around airfoil.I increased the no of nodes near the leading edge to capture the curvature. I need help with meshing around the curvature of Leading edge. And also whether this type of grid around LE is recommended to go with. I hope I am clear with description of the problem... Can someone help me with this? Thank you in advance. Regards Sathya |
