Hi,
I have some issues with converting my mesh to openfoam from gambit, going via ICEM.
If i I simply use the fluentMeshToFoam fluent.msh in openfoam it is no issue, but if i first import it in icem, output it without doing anyting and again running fluentMeshToFoam, I get this error:
--> FOAM FATAL ERROR:
Cannot find match for first face. cell model: hex first model face: 4(0 4 7 3) Mesh faces:
6
(
0()
0()
0()
0()
0()
0()
)

Is there something I have to do inside ICEM before the output, changing boundary conditions etc?
Of course I am changing some stuff in ICEM before outputting it, but since this doesnt work I have to start with this.
Any ideas?
Ansys people answers are appreciated.

-mAx- will become famous soon enough
try also:
fluent3DMeshToFoam
I use this one, when I generate tet-hexcore grids, where there are hanging nodes-

Let us know if -mAx-'s suggestion doesn't work and we will investigate on the ICEM CFD output side.

Also let us know what version of ICEM CFD you are using.

I'm using the ICEM 12.0.1
Yeah it works but not for my purpose, since I want to use the fluentMeshToFoam -writeSets alternative. This doesnt work for the fluent3dMeshToFoam
It would be very nice if you could find out what the issue might be

Yea, I think a bunch of work was done to make sure the Fluent output was perfect for 12.1... If you can try 13.0 you will probably find it is fine.

If you are up for working with me on this, I could send you a basic test case (just something basic like a few elements in a box), output from versions 12.0.1, 12.1, and 13 (and the 14.0 Preview 2 release) for you to test.

Just send me a private note with your email address if you are interested.

Hey Rick,

I totally missed this response (I don't have as much time for CFD-Online as I used to). If you are still up for testing this, let me know via a private message.

I would just send the samples anyway, but I figured you agreed to that quite a while ago and may not have time for it anymore...

Best regards,
