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.

--> FOAM FATAL ERROR:
Illegal cell label -1 in neighbour addressing for face 15671278

From function polyMesh::initMesh()
in file meshes/polyMesh/polyMeshInitMesh.C at line 65.

FOAM exiting


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.

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.
Regards
Saeed
