hi,
I'm trying to visualize my mesh witch i already verify with chekMesh and every things seems to be ok, using foamToVTK, since I use OpenFoam for simulation. the mesh was created under gmsh and converted by gmshToFoam command. I want to do this before actually computing anything but it crach with the following error message: Time 0 volScalarFields : p nuTilda k omega volVectorFields : U volTensorFields : R Internal : "/home/ouafa.bouloumou/work/RANScanal/jonction1/VTK/jonction1_1.vtk" Original cells:4430284 points:4558642 Additional cells:0 additional points:0 Cannot find face 13418476 in any of the patches 8 ( wall2 wall6 inlet2 wall4 wall5 inlet1 outlet wall1 ) It seems your patches are not consistent with the mesh : internalFaces:13163224 total number of faces:13418480#0 Foam::error:rintStack(Foam::Ostream&) in "/home/ouafa.bouloumou/OpenFOAM/OpenFOAM-1.5/lib/linux64GccDPOpt/libOpenFOAM.so" #1 Foam::error::abort() in "/home/ouafa.bouloumou/OpenFOAM/OpenFOAM-1.5/lib/linux64GccDPOpt/libOpenFOAM.so" #2 Foam:olyBoundaryMesh::whichPatch(int) const in "/home/ouafa.bouloumou/OpenFOAM/OpenFOAM-1.5/lib/linux64GccDPOpt/libOpenFOAM.so" #3 Foam:ointPatchInterpolation::makePatchPatchWeigh ts() in "/home/ouafa.bouloumou/OpenFOAM/OpenFOAM-1.5/lib/linux64GccDPOpt/libfiniteVolume.so" #4 Foam:ointPatchInterpolation:ointPatchInterpola tion(Foam::fvMesh const&, Foam:ointMesh const&) in "/home/ouafa.bouloumou/OpenFOAM/OpenFOAM-1.5/lib/linux64GccDPOpt/libfiniteVolume.so" #5 Foam::volPointInterpolation::volPointInterpolation (Foam::fvMesh const&, Foam:ointMesh const&) in "/home/ouafa.bouloumou/OpenFOAM/OpenFOAM-1.5/lib/linux64GccDPOpt/libfiniteVolume.so" #6 main in "/home/ouafa.bouloumou/OpenFOAM/OpenFOAM-1.5/applications/bin/linux64GccDPOpt/foamToVTK" #7 __libc_start_main in "/lib64/libc.so.6" #8 Foam::regIOobject::readIfModified() in "/home/ouafa.bouloumou/OpenFOAM/OpenFOAM-1.5/applications/bin/linux64GccDPOpt/foamToVTK" From function label polyBoundaryMesh::whichPatch(const label faceIndex) const in file meshes/polyMesh/polyBoundaryMesh/polyBoundaryMesh.C at line 402.

Have you tried checkMesh before running your model?

To me, there is definitely something inconsistent in your mesh. Check your mesh again and try to use a sketch for better understanding.

ok, i re-check the mesh and i get this:
Time = constant Mesh stats points: 1080154 faces: 3160732 internal faces: 3082172 cells: 1040484 boundary patches: 8 point zones: 0 face zones: 1 cell zones: 57 Number of cells of each type: hexahedra: 1040484 prisms: 0 wedges: 0 pyramids: 0 tet wedges: 0 tetrahedra: 0 polyhedra: 0 Checking topology...

Max volume = 7.74162e-09. Total volume = 0.00101256. Cell volumes OK. Mesh non-orthogonality Max: 42.2568 average: 4.83306 Non-orthogonality check OK. Face pyramids OK. Max skewness = 0.586609 OK. Mesh OK. End maybe it is about the "non-closed singly connected" topology? shoud i redefine all my patches? ouafa. |

The code start the calculation, right?
If it is, please do foamToVTK -time (the first time here) and see the result. |
