Hi all,
I'm new user and I'm meshing a tank with the blockMesh tool. Since I want to generate concentric cylinders inside the tank, I have created different cylinders, but due this apporoach the mesh overlap. Does anybody know which could be the best strategy to avoid this issue? Thanks, Fabio My blockmeshDict file: FoamFile { version 2.0; format ascii; root ""; case ""; instance ""; local ""; class dictionary; object blockMeshDict; } // * * * * * * * * * * * * * * * * * * * * * * * * * *// //meshGenApp blockMesh; convertToMeters 0.001; vertices ( ( 3.1819805 -3.1819805 0.0) ( 3.1819805 3.1819805 0.0) ( -3.1819805 3.1819805 0.0) ( -3.1819805 -3.1819805 0.0) ( 3.1819805 -3.1819805 150.0) ( 3.1819805 3.1819805 150.0) ( -3.1819805 3.1819805 150.0) ( -3.1819805 -3.1819805 150.0) ( 175.3624817 -175.3624817 150.0) ( 175.3624817 175.3624817 150.0) ( -175.3624817 175.3624817 150.0) ( -175.3624817 -175.3624817 150.0) ( 175.3624817 -175.3624817 1070.0) ( 175.3624817 175.3624817 1070.0) ( -175.3624817 175.3624817 1070.0) ( -175.3624817 -175.3624817 1070.0) ( 21.2132034 -21.2132034 150.0) ( 21.2132034 21.2132034 150.0) ( -21.2132034 21.2132034 150.0) ( -21.2132034 -21.2132034 150.0) ( 21.2132034 -21.2132034 1070.0) ( 21.2132034 21.2132034 1070.0) ( -21.2132034 21.2132034 1070.0) ( -21.2132034 -21.2132034 1070.0) ); blocks ( hex (0 1 2 3 4 5 6 7) (30 30 100) simpleGrading (1 1 1) hex (8 9 10 11 12 13 14 15) (20 20 100) simpleGrading (1 1 1) hex (16 17 18 19 20 21 22 23) (20 20 100) simpleGrading (1 1 1) ); edges ( arc 2 1 (0.0 4.5 0.0) arc 1 0 (4.5 0.0 0.0) arc 0 3 (0.0 -4.5 0.0) arc 3 2 (-4.5 0.0 0.0) arc 6 5 (0.0 4.5 150.0) arc 5 4 (4.5 0.0 150.0) arc 4 7 (0.0 -4.5 150.0) arc 7 6 (-4.5 0.0 150.0) arc 10 9 (0.0 248.0 150.0) arc 9 8 (248.0 0.0 150.0) arc 8 11 (0.0 -248.0 150.0) arc 11 10 (-248.0 0.0 150.0) arc 14 13 (0.0 248.0 1070.0) arc 13 12 (248.0 0.0 1070.0) arc 12 15 (0.0 -248.0 1070.0) arc 15 14 (-248.0 0.0 1070.0) arc 18 17 (0.0 30.0 150.0) arc 17 16 (30.0 0.0 150.0) arc 16 19 (0.0 -30.0 150.0) arc 19 18 (-30.0 0.0 150.0) arc 22 21 (0.0 30.0 1070.0) arc 21 20 (30.0 0.0 1070.0) arc 20 23 (0.0 -30.0 1070.0) arc 23 22 (-30.0 0.0 1070.0) ); patches ( patch inlet ( (0 3 2 1) (8 11 10 9) (16 19 18 17) ) patch outlet ( (4 5 6 7) (12 13 14 15) (20 21 22 23) ) ); mergePatchPairs ( ); // ************************************************** *********************** // |
