I am quite desperately looking for a mesher to create complex 3d as well as relatively simple 2d meshes.
I have tried using Salome but am finding it tricky, so have decided to use Ansys mesher for now, as I have acess to it at university, but hope that this is not a long-term solution as the program is to cluttered for my taste. In the meantime though, this is what I will use. I have exported the mesh file in Ansys Mesh as a .msh file and then placed it is the PolyMesh directory. I then ran fluentMeshToFoam from the polyMesh directory and get this output: Code:
/*---------------------------------------------------------------------------*\ | ========= | | | \\ / F ield | OpenFOAM: The Open Source CFD Toolbox | | \\ / O peration | Version: 2.3.0 | | \\ / A nd | Web: www.OpenFOAM.org | | \\/ M anipulation | | \*---------------------------------------------------------------------------*/ Build : 2.3.0-f5222ca19ce6 Exec : fluentMeshToFoam constant/polyMesh/SYS.msh Date : Aug 25 2014 Time : 21:14:50 Host : "mich-TravelMate-8372" PID : 18804 Case : /home/mich/CFDStore/Base_case/case 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 number of faces: 8110 Number of points: 3060 Reading uniform faces Reading points FINISHED LEXING #0 Foam::error::printStack(Foam::Ostream&) at ??:? #1 Foam::sigSegv::sigHandler(int) at ??:? #2 in "/lib/x86_64-linux-gnu/libc.so.6" #3 at ??:? #4 __libc_start_main in "/lib/x86_64-linux-gnu/libc.so.6" #5 at ??:? Segmentation fault (core dumped) mich@mich-TravelMate-8372:~/CFDStore/Base_case/case$ I am fairly sure the .msh file is in ASCII format. Will it be able to import the named selections from Ansys Mesh? Thank you in advance.

There is another tool call fluentMeshToFoam which works (sometimes) if fluent3DMeshToFoam does not work.
See http://openfoamwiki.net/index.php/Fluent3DMeshToFoam |
