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:

What am I doing wrong?

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

Hi, I have a similar problem here, I am using CAE Linux 2013

After execute dos2unix fluent.msh

And show me:
dos2unix: Skipping binary file Helical2.msh

Then I execute fluent3dMeshToFoam and shows as follow:

Did your case solved ? I have the exact same problem with fluentMeshtoFoam as well. I willing to know how to solve this problem.
