Hello Foamers，

I tried to import my .msh format fluent mesh from ICEM-CFX to Openfoam.
I can open this mesh with fluent easily. When I decided to import it to Openfoam, suddenly I saw this error during the conversion.

I prepared this mesh in 3D format ( 2D with just one cell thickness ) for simulation. I want to know what should I do to omit this error? What does it mean by illegal cell label?
I am looking forward to hearing from you.
Any suggestion would be appreciated.

I have the same error as you.
Please let us know how to omit this error.
Thank you Foamers.

A way for importing the mesh with this error to Foam is found.
Firstly, try to open it in Fluent with .msh data, then make a save as .cas format.
At the end, write this comment in your terminal.
FluentMeshToFoam <name of file>.cas
It should be worked.
