Hi
I have created a mesh in ICEM and the mesh checked is ok without any error. I imported it into OpenFoam and conduct the meshCheck. it failed due to 1 skew face. I tried reading into fluent and the mesh is ok as well. How can I locate the skew face in ICEM and repair it? Also in Openfoam, what is the limit in skewness and how does it define skewness? Thanks a lot for any advice |

When you run checkMesh, does it write out the skew face sets? If so, you could probably use the setSet or setsToZones utility to create *.vtk files to locate the skew faces.
I think this is where the skewness is computed in openfoam - http://foam.sourceforge.net/docs/cpp...ce.html#l00523 . Kind regards, Kevin |

Hi
Thanks for the reply. How do I use the setToZones utility? The checkMesh does wrote out the set that is a skew face. Thanks |

Hi,
openfoam can handle cases where checkMesh returns failed. To my knowledge, checkMesh was write in a time when openFOAM wasn't as stable as it is today. If the mesh is ok in ICEM, it should be ok. How to locate "bad cells", have a look at this thread: http://www.cfd-online.com/Forums/ope...-paraview.html Regards, Christian |

Hi,
skewedFaces are normally not a problem. In general you are able to solve your case but sometimes the faces make problems. The sets you wanna visual in paraview is very easy to handle: Code:
foamToVTK -faceSet skewedFaces (or sth. like that) Utility setSet |
