Hi Everyone!,
I have been trying to mesh using snappyHexMesh a rectangular domain with a cylinder inside. Although I was able to mesh it, the surface mesh is not that good. Also the edges with layers are having bad elements. I will be using icoLagrangianFoam solver and good surface mesh is important. I am attaching the snappyHexMesh file. Can anyone look through this and tell me what can i modify to improve the mesh quality. ![]() ![]() ![]() Thanks in advance Regards Subhasree |

I got the following error when i tried to get the .eMesh file from the .stl file. Is there any problem with my openfoam installation. Do I need to reinstall the entire thing once again?
Code:
$ surfaceFeatureExtract -includedAngle 150 -writeObj constant/triSurface/airfoil.stl airfoil Usage: surfaceFeatureExtract [OPTIONS] options: -case <dir> specify alternate case directory, default is the cwd -dict <file> read control dictionary from specified location -noFunctionObjects do not execute functionObjects -srcDoc display source code in browser -doc display application documentation in browser -help print the usage extract and write surface features to file Using: OpenFOAM-3.0.1 (see www.OpenFOAM.org) Build: 3.0.1-d8a290b55d28 --> FOAM FATAL ERROR: Wrong number of arguments, expected 0 found 3 Invalid option: -writeObj Invalid option: -includedAngle FOAM exiting |

Hi,
Your format for surfaceFeatureExtract is based on OF-2.1 and possibly older. The new ones from OF-2.2 require a surfaceFeatureExtractDict where you specify the includedAngle and the like... Cheers, Antimony |
