hii every one
i am new to openFoam and trying to creat circular patch for particle injection of patch injection model and getting this error while creating circle please help me with this face 0 in patch 2 does not have neighbour cell face: 4(8 10 9 8) convertToMeters 0.001; vertices ( (-7.5 -75 0) //0 ( 7.5 -75 0) //1 ( 7.5 75 0) //2 (-7.5 75 0) //3 (-7.5 -75 450) //4 ( 7.5 -75 450) //5 ( 7.5 75 450) //6 (-7.5 75 450) //7 (0 0 0) //8 (0 2 0) //9 (0 -2 0) //10 ); blocks ( hex (0 1 2 3 4 5 6 7) (1 15 45) simpleGrading (1 1 1) ); edges ( arc 9 10 (-2 0 0) arc 10 9 (2 0 0) ); boundary ( top { type patch; faces ( (4 5 6 7) ); } bottom { type patch; faces ( (0 3 2 1) ); } circle { type patch; faces ( (8 10 9 8) (8 9 10 8) ); } walls { type wall; faces ( (0 1 5 4) (2 3 7 6) ); } frontAndBack { type symmetry; faces ( (1 2 6 5) (3 0 4 7) ); } ); mergePatchPairs ( (bottom circle) ); https://drive.google.com/file/d/1QvD...ew?usp=sharing // ************************************************** *********************** |

Any face should either have a neighbour or a boundary condition. The face in question has non of these.

There are many sources for what you are looking for. First read OpenFOAM documentation - there is a fairly good explanation of how to use blockMesh. Additionally, from the top of my head, you could try the tutorials in the wiki page: https://wiki.openfoam.com/Meshing
Best, Petros |
