Hello everyone!
I'm new to FOAM and I'm setting up a case for a pressure-driven flow in a channel with a buffer zone. My blockMeshDict looks as follows: /*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: dev | | \\ / A nd | Web: www.OpenFOAM.com | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; class dictionary; object blockMeshDict; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // convertToMeters 1e-6; vertices ( (0 0 0) //0 (1.5 0 0) //1 (1.5 0.15 0) //2 (0 0.15 0) //3 (0 0 0.1) //4 (1.5 0 0.1) //5 (1.5 0.15 0.1)//6 (0 0.15 0.1) //7 (2.1 0 0) //8 (2.1 0.6 0) //9 (1.5 0.6 0) //10 (2.1 0 0.1) //11 (2.1 0.6 0.1) //12 (1.5 0.6 0.1) //13 (1.5 0.15 0) //14 (1.5 0.15 0.1)//15 (1.5 0 0.1) //16 (1.5 0 0) //17 (2.1 0.15 0) //18 (2.1 0.15 0.1) //19 ); blocks ( hex (0 1 2 3 4 5 6 7) (200 60 1) simpleGrading (1 1 1) hex (8 11 14 15 16 17 18 19) (50 50 1) simpleGrading (1 1 1) hex (9 10 12 13 14 15 18 19) (50 50 1) simpleGrading (1 1 1) ); edges ( ); patches ( patch Inlet ( (0 3 7 4) ) patch Outlet ( (11 8 18 19) (19 12 9 18) (9 12 13 10) ) wall Wall ( (14 10 13 15) (2 6 7 3) ) symmetry Symmetry ( (8 17 16 11) (5 1 0 4) ) empty Front_and_Back ( (0 1 2 3) (7 6 5 4) (17 8 18 14) (16 11 19 15) (14 18 9 10) (15 19 12 13) ) patch interface1 ( (2 6 5 1) ) patch interface2 ( (14 15 16 17) ) ); mergePatchPairs ( (interface1 interface2) ); // ************************************************** *********************** // When I use the blockMesh command, I get an error as follows: //face 0 in patch 2 does not have neighbour cell face: 4(14 10 13 15) I tried running blockMesh with only one block at a time and still got the same error for different faces. I've tried solutions found online but with no success Please help. Thanks in advance -Syracuse |
