Hi All,

sometimes when I build my mesh, using HyperMesh and then exporting it as a fluent mesh (file .cas) ) I receive this error message:

--> FOAM FATAL ERROR : Problem : cannot find a single face in the mesh which uses vertices 4(80040 80037 80039 80041)

From function findFace(const primitiveMesh&, const face&)
in file fluentMeshToFoam.L at line 855.

FOAM exiting


Can you tell me what to do? I checked the mesh and everything seems to be ok

Thanks in advance

Francesco

I found the error

I have built the mesh with Hypermesh 7, opened with the 8 and converted, if I build it in the 8 there is no error.

I hope this could be useful to someone else

Regards

Hi everyone. I received the same error.
The Mesh was generated with gambit and cannot be converted to Foam. I included some virtual edges/ points in order to mesh the interfaces.
The Mesh seems to be ok.

Thank you,

Michael

Could you please explain in more details what is exactly 'Hypermesh 7' and what does it do in the first place. I'm having same serious trouble with 'lost vertices' on every mesh that I generate.

Thanks a million!

I am also facing the same issue....Is this because of version of Gambit I am using, any solution will be highly appreciated.

Thankyou

Hello,

Unfortunately, I have same problem. It is a real SHAME to see this message after trying hard on mesh.

Regards,

Emre

I had the same issue a while ago.

The error was that i had a 2D mesh but while exporting my msh file, in the export option the 3D Model box was checked... Checking the 2D box solve the issue.

Another problem was that i had an internal wall BC but openfoam can't handle 1D wall elements inside the domain. So i had to give a surface to that wall by making holes in the domain.

Hope it will help.

Hi there guys, I am trying to create an *.msh file with Gmsh and then import this in openfoam. When I create the msh file and run fluentMeshToFoam I get


FINISHED LEXING


dimension of grid: 0
Creating shapes for 3-D cells
Building patch-less mesh...done.

Building boundary and internal patches.

Writing mesh... to "constant/polyMesh" done.


End


And there as you can imagine no mesh. Apparently I create something wrong. I am trying to find an .msh file available to see where the mistake might be and actually how it should look but haven't made. Does anyone have anything simple available just to see the structure of the file?


--------UPDATE-----------

I just found out that I need to "export" the mesh on Gmsh instead of just saving.

I am facing similar problem (cannot find a single face in the mesh which uses vertices 345968 5522 33610) in foam extend 4.0, and mesh is generated in Ansys 2020R2. Can anyone suggest me, how I can resolve this ASAP?

Thanks,
Best Regards,
Ram
