Hi Foamers,
I have a problem with the grid generation using blockMesh. With the setup included below I get the following output and error message from blockMesh: // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // Create time Creating block mesh from "/daten/ShipLES/geom_bodies/quader/LES/calc/snappy_LES/constant/polyMesh/blockMeshDict" Creating blockCorners Creating curved edges Creating blocks Creating patches Creating block mesh topology Default patch type set to empty Trying to specify a boundary face 4(2 3 7 6) on the face on cell 0 which is either an internal face or already belongs to some other patch. This is face 0 of patch 3 named Q_TOP.#0 Foam::error:rintStack(Foam::Ostream&) in "/usr/local/OpenFOAM/OpenFOAM-1.6.x/lib/linux64GccDPOpt/libOpenFOAM.so" #1 Foam::error::abort() in "/usr/local/OpenFOAM/OpenFOAM-1.6.x/lib/linux64GccDPOpt/libOpenFOAM.so" #2 Foam:olyMesh:olyMesh(Foam::IOobject const&, Foam::Xfer<Foam::Field<Foam::Vector<double> > > const&, Foam::List<Foam::cellShape> const&, Foam::List<Foam::List<Foam::face> > const&, Foam::List<Foam::word> const&, Foam::List<Foam::word> const&, Foam::word const&, Foam::word const&, Foam::List<Foam::word> const&, bool) in "/usr/local/OpenFOAM/OpenFOAM-1.6.x/lib/linux64GccDPOpt/libOpenFOAM.so" #3 Foam::blockMesh::createTopology(Foam::IOdictionary &) in "/usr/local/OpenFOAM/OpenFOAM-1.6.x/applications/bin/linux64GccDPOpt/blockMesh" #4 Foam::blockMesh::blockMesh(Foam::IOdictionary&) in "/usr/local/OpenFOAM/OpenFOAM-1.6.x/applications/bin/linux64GccDPOpt/blockMesh" #5 main in "/usr/local/OpenFOAM/OpenFOAM-1.6.x/applications/bin/linux64GccDPOpt/blockMesh" #6 __libc_start_main in "/lib64/libc.so.6" #7 Foam::regIOobject::writeObject(Foam::IOstream::str eamFormat, Foam::IOstream::versionNumber, Foam::IOstream::compressionType) const in "/usr/local/OpenFOAM/OpenFOAM-1.6.x/applications/bin/linux64GccDPOpt/blockMesh" From function polyMesh:olyMesh ( const IOobject&, const Xfer<pointField>&, const cellShapeList& cellsAsShapes, const faceListList& boundaryFaces, const wordList& boundaryPatchTypes, const wordList& boundaryPatchNames, const word& defaultBoundaryPatchType ) in file meshes/polyMesh/polyMeshFromShapeMesh.C at line 484.

When I look at the blocking with simpleViewer, everything seems to be well arranged. The blockMeshDict is as follows (it is a cuboid placed in the middle of a wide cylinder; I hope everything is commented sufficiently): /*--------------------------------*- C++ -*----------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: 1.6 | | \\ / A nd | Web: http://www.OpenFOAM.org | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ FoamFile { version 2.0; format ascii; class dictionary; object blockMeshDict; } // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // // Cuboid in Cylinder // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // convertToMeters 0.001; // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // vertices ( // Base Cuboid (-70.8 -70.8 0) // 0 (70.8 -70.8 0) // 1 (70.8 70.8 0) // 2 (-70.8 70.8 0) // 3 // Lid Cuboid (-70.8 -70.8 283) // 4 (70.8 -70.8 283) // 5 (70.8 70.8 283) // 6 (-70.8 70.8 283) // 7 // Empty Cuboid (-70.8 -70.8 850) // 8 (70.8 -70.8 850) // 9 (70.8 70.8 850) // 10 (-70.8 70.8 850) // 11 // Cylinder base (1414.2 1414.2 0) // 12 (0 2000 0) // 13 (-1414.2 1414.2 0) // 14 (-2000 0 0) // 15 (-1414.2 -1414.2 0) // 16 (0 -2000 0) // 17 (1414.2 -1414.2 0) // 18 (2000 0 0) // 19 // Middle plane cylinder (1414.2 1414.2 283) // 20 (0 2000 283) // 21 (-1414.2 1414.2 283) // 22 (-2000 0 283) // 23 (-1414.2 -1414.2 283) // 24 (0 -2000 283) // 25 (1414.2 -1414.2 283) // 26 (2000 0 283) // 27 // Cylinder Top (1414.2 1414.2 850) // 28 (0 2000 850) // 29 (-1414.2 1414.2 850) // 30 (-2000 0 850) // 31 (-1414.2 -1414.2 850) // 32 (0 -2000 850) // 33 (1414.2 -1414.2 850) // 34 (2000 0 850) // 35 ); blocks ( // Cuboid hex (0 1 2 3 4 5 6 7) quader (5 5 5) simpleGrading (1 1 1) // Empty Cuboid hex (4 5 6 7 8 9 10 11) (5 5 5) simpleGrading (1 1 1) // North-Quadrant on Cylinder Basis hex (3 2 12 14 7 6 20 22) (5 5 5) simpleGrading (1 1 1) // West-Quadrant on Cylinder Basis hex (0 3 14 16 4 7 22 24) (5 5 5) simpleGrading (1 1 1) // South-Quadrant on Cylinder Basis hex (1 0 16 18 5 4 24 26) (5 5 5) simpleGrading (1 1 1) // East-Quadrant on Cylinder Basis hex (2 1 18 12 6 5 26 20) (5 5 5) simpleGrading (1 1 1) // North-Quadrant on Cylinder Top hex (7 6 20 22 11 10 28 30) (5 5 5) simpleGrading (1 1 1) // West-Quadrant on Cylinder Top hex (4 7 22 24 8 11 30 32) (5 5 5) simpleGrading (1 1 1) // South-Quadrant on Cylinder Top hex (5 4 24 26 9 8 32 34) (5 5 5) simpleGrading (1 1 1) // East-Quadrant on Cylinder Top hex (6 5 26 20 10 9 34 28) (5 5 5) simpleGrading (1 1 1) ); edges ( // Arc Basis Cylinder arc 12 14 (0 2000 0) // arc 0 arc 14 16 (-2000 0 0) // arc 1 arc 16 18 (0 -2000 0) // arc 3 arc 18 12 (2000 0 0) // arc 4 // Arc middle plane arc 20 22 (0 2000 283) // arc 5 arc 22 24 (-2000 0 283) // arc 6 arc 24 26 (0 -2000 283) // arc 7 arc 26 20 (2000 0 283) // arc 8 // Arc Top Cylinder arc 28 30 (0 2000 850) // arc 9 arc 30 32 (-2000 0 850) // arc 10 arc 32 34 (0 -2000 850) // arc 11 arc 34 28 (2000 0 850) // arc 12 ); patches ( // Cylinder shell patch ZYL_AUSSEN ( // Cylinder shell, on cylinder Basis (12 14 22 20) // North (14 16 24 22) // West (16 18 26 24) // South (18 12 20 26) // East // Cylinder shell, on Cylinder Top (20 22 30 28) // North (22 24 32 30) // West (24 26 34 32) // South (26 20 28 34) // East ) // Cylinder Top patch ZYL_TOP ( (28 30 11 10) // North (30 32 8 11) // West (32 34 9 8) // South (34 28 10 9) // East (8 9 10 11) // Center Cylinder Top ) // Cylinder Basis patch ZYL_BASE ( (2 3 14 12) // North (3 0 16 14) // West (0 1 18 16) // South (1 2 12 18) // East (3 2 1 0) // Center Cylinder Basis ) wall Q_TOP ( (2 3 7 6) ) wall Q_FRONT ( (1 2 6 5) ) wall Q_BOTTOM ( (0 1 5 4) ) wall Q_BACK ( (0 4 7 3) ) wall Q_LID ( (4 5 6 7) ) ); // ************************************************** *********************** // Cheers, Pascal. |
