Hello everybody,
I have a problem using stitchMesh utility. When I want to stitch two interfaces i have a duplicate point error : Code:
Duplicate point found in cut face. Error in the face cutting algorithm for global face 4(53292 53293 54193 54192) local face 4(0 1 2 3) Slave size: 240 Master size: 917 index: 0. Face: 10(53292 55407 55408 55092 55165 55164 55163 55166 54193 54192) Nolwenn |

Hi Nolwenn,

Hi Rebecca and Nolwenn,
I am having the same problem. Did you figure out a solution? I read on the forum, we should use a -perfect flag for stitchMesh, but when i used it, I got the following error message. Quote:
Thanks, Dhruv. |

Hi Dhruv,
the -perfect flag actually worked for me. Are the two patches you are working on 100% the same? Maybe you can try other flags? Best, |

Did anybody find the solution for this?
I also get Duplicated Points and can't figure out how to get rid of them. Thanks a lot! |

Hi Dhruv,
I have right now the same problem trying to merge a rectangular block (1) into a mesh with a rectangular hole (2). Bounding boxes of block (1) and hole (2) are identical, but points and faces at the interface are different. The executed command is the following: stitchMesh -overwrite -perfect INTERFACE defaultFaces Did you find out a solution for the quoted issue? Quote:
Code:
--> FOAM FATAL ERROR: Points on patch sides do not match to within tolerance 1.45655e-05 From function perfectInterface::setRefinement(polyTopoChange& ref) const in file perfectInterface/perfectInterface.C at line 220. FOAM exiting Best regards, Andrea |

Hello,
I get: --> FOAM FATAL ERROR: Duplicate point found in cut face. Error in the face cutting algorithm for global face when using stitchMesh. The interfaces are the same but with different resolution and complex cells. Any hints or maybe improvements with OF 2.3 ? |

Try increasing a little bit the tolerance, that worked for me.
I have also heard that performing operations such as stitching in binary might also help since it will reduce roudn off arithmetic errors |

I want to merge a mesh to tranlated version of himself with stitchMesh -perfect.
The Mesh on the surfaces are exactly the same (i see in paraview), but i got the dam error "Points on patch sides do not match with ..." Why?? I am very desperated. Can someone tell me whats going on? Can i force him to stitch the meshes cause i know, they are the same. |

I know this is an old thread but for future use, I mention my experience for this error.
I had the same error with my blockMesh. In my case, I did not define the edges well . After well defining the edges ( for circle in geometry) the problem was solved. Hope it helps. |
