Generating Mesh - NACA0012 Airfoil

I am trying to generate a mesh of a NACA0012 airfoil and then run a case with water and air running over the airfoil. I have an stl file of the airfoil and have attempted to convert this to a blockMeshDict file to be able to modify the airFoil2D tutorial case and use blockMesh to generate the mesh, but haven't had any luck. I am very new to OpenFOAM and CFD concepts, so I may be going about this entirely the wrong way. I am using Ubuntu 12.04 and OpenFOAM-2.2.0.
Any help pointing me in the right direction, such as how to correctly generate the mesh, what solvers to use, etc., would be greatly appreciated! |

welcome to forum
first of all, you can find your solution faster by search in forum, forexample search airfoil, NACA and so on , i made it for you, and some interesting link is below: http://www.cfd-online.com/Forums/ope...-aerofoil.html or http://www.cfd-online.com/Forums/ope...-naca0012.html in brief, you have two choice: 1- using blockMesh ( create a Cmesh around airfoil) 2-uisng snappyHexMesh if you have stl file

Thanks for the quick reply, although I have already searched the forum and have read both of those threads. Either the person who posted the thread had some information previously that I did not have or there were parts of the given solution that I didn't understand, so that's why I decided to post my own question.

I think you should follow the wingMotion tutorial. You could find it under incompressible/pimpleDyMFoam.
Check the Allrun file. Basically, you will have to follow the following steps; 1 - Generate .stl file using any CAD program like FreeCAD. 2 - Create background mesh using blockMesh 3 - Using snappyHexMesh to create your mesh 4 - use extrudeMesh to create 2D mesh And to achieve a good yPlus value for your case you could use refineWallLayer Also you could use blockMesh only which I am not prefer. I use it only for simple cases. |
