Hallo,
i want to create a relative complex 2D mesh for OpenFOAM (still 3D but with one cell in z-direction). I know i can do this with blockMesh, but since my geometry is very complex i am searching for a solution where i can create it a little bit simpler than just hacking all the points and stuff in the blockMeshDict. Is it possible to make a pseudo 2D mesh with snappyHexMesh? greetings from Munich, Germany... draufunddran |

hi friend
look at following website , its a free software for mesh creating  and work with openFoam and its easy to work http://www.discretizer.org/ |

Hallo,
i have tried some thinks with Discretizer, but i think its not what i'm looking for. I can't make a 2D-mesh of an airfoil. Some informations on my case: I need to calculate the drag and lift of different 2D-airfoils with OpenFOAM and i don' have any commercial meshing applications. Are there any other free meshing tools out there? Thanks for your support... draufunddran |

Dear Draufunddran:
Have you tried with Gmsh? I 'm experimenting a little bit with gmsh trying to calculate the velocity field with potentialFoam with no good results to the NACA0015 airfoil. My test: inlet = 10m/s, slip conditions and the cp should be near -0.57 so I should obtain velocities over the airfoil 25% over than Uinf. I can email you my results.
