Hi all,

I have tried to re-create the mixerVessel2D mesh in ICEM CFD. In this mesh, both the impeller blades and the the baffles at the tank wall have zero thickness.

I have successfully imported this mesh in Fluent (which, as expected, creates shadow walls for these zero-thickness walls).

However, when I try to convert the .msh file using fluent3DMeshToFoam I get te following error:

The mesh file is attached.

Any idea of what's going on here?
