[Other] Converting mesh from Fluent 21.1

xuegy · October 18, 2021, 11:41

Hello all,

I'm converting a fluent polyhedra mesh to OpenFOAM. I'm sure that fluent3DMeshToFoam works with Fluent 17.1 .cas file.
Recently we have upgraded to ANSYS 2021 R1 and now fluent can only export to .cas.h5 or .cas.gz and none of them can be recognized by OpenFOAM.
I even tried to use TUI with no luck

Code:

/file> binary-legacy-files
Write binary files? [yes] no
/file> write-case

Anyone knows if there's a workaround? Thanks.

Proceed in two steps:

(1/2): gunzip your-file.cas.gz

(2/2): apply previous to your-file.cas

Still doesn't work. However the unzipped .cas file can be opened by Paraview.

Hi,

For someone who has the same problem, I have written the solution procedure here:

Error in polyhedral-mesh (Fluent Meshing) conversion to OpenFOAM.
