Hi Kevin,
What airfoil do you have in mind? NACA0015.... I assume you're using an o-mesh but where's the inlet in your definitions?! What are your mesh parameters incl. y+, #cells along the surface (about 300?), #cells in z-direction (about 140?)? Here you can calculate your case specific turbulence properties: https://www.cfd-online.com/Tools/turbulence.php Please post your boundary file from the constant/polyMesh directory. Klaus |

Thank you for your reply. My calculated airfoil is DU-93-W-210. I use icem to generated a C-H type mesh, it was realized as follows (1) generate a 2d airfoil unstructured mesh in the x, y directions (2) extrude the mesh in the z direction. Since openfoam only accept the 3d unstructured mesh. For the inlet, it is a line in the 2d mesh. So, I delete in in the 3d mesh after extruding. Is that right? Please find the boundary information in the attached file. Thank you. boundary.JPG |
