[Commercial meshers] Importing Fluent polyhedral meshes

fra76 · February 22, 2007, 06:02

Hi all!
I'm trying to convert a fluent polyhedral mesh to OpenFOAM using fluentMeshToFoam. The mesh is a tgrid "hexcore" mesh, saved as polyhedra.
when I try to convert it, I get this error message:

Found unknown block in zone
Found end of section in unknown

FINISHED LEXING

dimension of grid: 3
Creating shapes for 3-D cells

--> FOAM FATAL ERROR : unrecognised 3-D cell shape: 7

From function fluentToFoam::main(int argc, char *argv[])
in file fluentMeshToFoam.L at line 1074.

FOAM aborting

Foam::error::printStack(Foam:: Ostream&)
Foam::error::abort()
fluentMeshToFoam [0x40e624]
__libc_start_main
__gxx_personality_v0
Aborted

3D cell type "7", in Fluent notation, is a polyhedral cell.
Is there a way to convert such a mesh?
Any suggestion will be appreciated!

Hi all!
I met the same problem. Is it a bug or fluentToFoam does not have this function ?

Hi,
try fluent3DMeshToFoam, if the mesh is 3D. It should work.
