Hello!
I am new with OF and have just run some tutorial examples up to now. Recently I wanted to start my own simulations and compare them to ansys results. I have created a model geometry and Mesh in Ansys Worbench 12 ( where Fluent is included) on a WinXp32 machine and exported a .msh file from fluent. In the Fluent launcher I've added the environment Variable AWP_WRITE_FLUENT_MESH_ASCII=1 Restarting the machine on Ubuntu i execute Code:
$dos2unix -b myMesh.msh Then I've tried to convert the Mesh with fluentMeshToFoam , because it's a 2D Mesh Code:
$ fluentMeshToFoam quader2_envVarFluent.msh /*---------------------------------------------------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: 1.6 | | \\ / A nd | Web: www.OpenFOAM.org | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ Build : 1.6-53b7f692aa41 Exec : fluentMeshToFoam quader2_envVarFluent.msh Date : Mar 31 2010 Time : 12:08:40 Host : BE13661 PID : 2337 Case : /media/System/Claus/GasSimu/OpenFoam/valve_All_2D nProcs : 1 SigFpe : Enabling floating point exception trapping (FOAM_SIGFPE). // * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * * // Create time number of faces: 402 Number of points: 56 Reading uniform faces Reading uniform faces Reading uniform faces Reading points FINISHED LEXING #0 Foam::error::printStack(Foam::Ostream&) in "/home/claus/OpenFOAM/OpenFOAM-1.6/lib/linuxGccDPOpt/libOpenFOAM.so" #1 Foam::sigSegv::sigSegvHandler(int) in "/home/claus/OpenFOAM/OpenFOAM-1.6/lib/linuxGccDPOpt/libOpenFOAM.so" #2 Uninterpreted: #3 main in "/home/claus/OpenFOAM/OpenFOAM-1.6/applications/bin/linuxGccDPOpt/fluentMeshToFoam" #4 __libc_start_main in "/lib/tls/i686/cmov/libc.so.6" #5 _start at /usr/src/packages/BUILD/glibc-2.9/csu/../sysdeps/i386/elf/start.S:122 Segmentation fault Code:

FOAM exiting Does anyone have an idea what could be wrong ? How to check if the ASCII export was done properly ? The file is on a windows ntfs partition which I access from ubuntu which was installed on another partition. Thank you for your help! Last edited by archymedes; March 31, 2010 at 07:57. |

I've found a solution.
Up to now I have tried to export a .msh file from Fluent and then read it with OF. As I create my geometry and mesh in Ansys Workbench, I now export the .msh file from the Workbench Mesher! Then I execute dos2unix, and now it can be read by fluentMeshToFoam wihout any errors! I don't know why the Fluent export doesn't work, but at least it works with the ansys mesher.
