I built a simple mesh in gambit that I need in openFOAM, however, everytime i try to convert i always get this:

In Gambit, select Fluent Solver.
Export your *.msh mesh-file.
Then in OpenFOAM, > fluentMeshToFoam your_file.msh
...
If you used Hexcore with hanging nodes, then you need to convert your mesh file with tpoly utility from Fluent.
Then in OpenFOAM, > fluent3DMeshToFoam your_file.msh

fluentMeshToFoam is giving me the error -

Problem : cannot find a single face in the mesh which uses vertices 4(61206 61208 61316 61315)

From function findFace(const primitiveMesh&, const face&)
in file fluentMeshToFoam.L at line 858.

So that isn't working either, and the mesh is just a simple cube as well.

have you boult a 2d, or 3d mesh?
what kind of cells? (hexa, tetra, prism)?
have you set the BC?

By the way, I see you have linux 64bit: do you have also fluent for linux 64bit?
I need the installation file (for using the tpoly utility)

I actually have linux 64 bit on at a different location I'm running 32 bit on both on this location. And its a 3d mesh with hex cells, what file did you say you needed?

I need the tpoly utility from Fluent 64bit (linux version).
Regarding your mesh, it should work.
can you paste the errors from the fluentMeshToFoam.

Ok I checked the thread.
Can you provide your mesh file? or the dbs file
I never had any problem from gambit (windows) into OpenFOAM
