Hi.
I've a big issue that I can't understand. After the fluent3DMeshToFoam command, i would like to know if my mesh was good enough so .... checkMesh.... and that's what i received from the command windows : /*---------------------------------------------------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: 1.7.x | | \\ / A nd | Web: www.OpenFOAM.com | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ Build : 1.7.x-4bbf33160caf Exec : checkMesh Date : Feb 09 2011 Time : 14:02:20 PID : 4947 Case : /home/Ares nProcs : 1 SigFpe : Enabling floating point exception trapping (FOAM_SIGFPE). // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // Create time Create polyMesh for time = 0 --> FOAM Warning : From function polyMesh(const IOobject&) in file meshes/polyMesh/polyMesh.C at line 307 no cells in mesh Time = 0 Mesh stats points: 107901 internal points: 0 #0 Foam::error:rintStack(Foam::Ostream&) in "/opt/openfoam171/lib/linuxGccDPOpt/libOpenFOAM.so" #1 Foam::sigSegv::sigSegvHandler(int) in "/opt/openfoam171/lib/linuxGccDPOpt/libOpenFOAM.so" #2 Uninterpreted: #3 Foam:rimitiveMesh::calcCells(Foam::List<Foam::ce ll>&, Foam::UList<int> const&, Foam::UList<int> const&, int) in "/opt/openfoam171/lib/linuxGccDPOpt/libOpenFOAM.so" #4 Foam:rimitiveMesh::calcCells() const in "/opt/openfoam171/lib/linuxGccDPOpt/libOpenFOAM.so" #5 Foam:rimitiveMesh::cells() const in "/opt/openfoam171/lib/linuxGccDPOpt/libOpenFOAM.so" #6 in "/opt/openfoam171/applications/bin/linuxGccDPOpt/checkMesh" #7 in "/opt/openfoam171/applications/bin/linuxGccDPOpt/checkMesh" #8 __libc_start_main in "/lib/libc.so.6" #9 in "/opt/openfoam171/applications/bin/linuxGccDPOpt/checkMesh" Erreur de segmentation If someone could help me to understand this error. thanks a lot |

If I was you, I would focus on this line...
no cells in mesh |

It's strange .... because when I put fluent3DtoFoam, it tells me that I've over 13000 cells in my mesh ... so ...maybe i've to change another file before running check mesh ? what do you think ?

did you try fluentMeshToFoam instead of fluent3DMeshToFoam?
I use fluent3DMeshToFoam if I have hanging nodes in my mesh (tetra-hexcore mesh). Else I use fluentMeshToFoam
