hi friends im worked in a tutorial case were to create a snappyhexmesh i get the stl file and snappyhexmeshdict in that folder right. but im gettting error saying "Number of cells in mesh:3840 does not equal size of cellLevel:18922
This might be because of a restart with inconsistent cellLevel." i created the snappy hex mesh after typing blockmesh can anyone help me in find out were i going wrong /*---------------------------------------------------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: 2.1.0 | | \\ / A nd | Web: www.OpenFOAM.org | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ Build : 2.1.0-0bc225064152 Exec : snappyHexMesh Date : Jan 25 2012 Time : 16:03:18 Host : "kirubha-AcerPower-Series" PID : 2279 Case : /home/kiruhbhakaran/tutorials/mesh/snappyHexMesh/flange nProcs : 1 sigFpe : Enabling floating point exception trapping (FOAM_SIGFPE). fileModificationChecking : Monitoring run-time modified files using timeStampMaster allowSystemOperations : Disallowing user-supplied system call operations // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // Create time Create mesh for time = 0 Read mesh in = 0.04 s Overall mesh bounding box : (-0.03 -0.03 -0.03) (0.03 0.03 0.01) Relative tolerance : 1e-06 Absolute matching distance : 9.38083e-08 Reading refinement surfaces.

Delete your old timestep folders, and *Level in constant/polyMesh.
Hope this helps |

Dear foamers,
i have problem in snappy hex mesh, i have cad model in stl format,how i solve in open foam, 1.how to import 2.how to create outer domain 3.how to mesh the model 4.how to set boundary condition,for my i consider to create domain to set inlet velocity ,pressure outlet and remaining face is symmetry wall is cad model 5.how to run i am begineer please give idea for to this problem |

Hi hhh,
1-5) Please read the manual, that you can find in your OpenFOAM folder under doc/Guides-*/UserGuide.pdf. |
