Hi all together,

in the picture you can see the geometry (created with salome).
The colored faces are internalFaces

Green: wanna get it as a wall
lightblue: wanna get it as fan

I convert it to UNV and with IdeasToFoam Mesh_1 i got my OF mesh. I get my boundarys for the external faces "wall and frontAndBack"...

Of 18692 so-called boundary faces 976 belong to two cells and are therefore internal
Sorting boundary faces according to group (patch)
0: fan is faceZone
1: internalWall is faceZone
2: wall is patch
3: frontAndBack is patch

Constructing mesh with non-default patches of size:
    wall    1212
    frontAndBack    16504

Adding cell and face zones
 Face Zone internalWall     616
 Face Zone fan     360

End

I got the other two faces into the faceZone (polyMesh/)

So now the question, how can i create a patch onto those internalFaces ? :/
Never done this befor and i don 't know how to do this.

So if its not clear i wanna have: (short)

--> in the boundary file i would have the entrys

frontAndBack
wall
internalWall
fan

Now my boundary file looks like

2
(
    wall
    {
        type            patch;
        nFaces          1212;
        startFace       63116;
    }
    frontAndBack
    {
        type            patch;
        nFaces          16504;
        startFace       64328;
    }
)

So is there a tool which i can make the FaceZones (internalWall and fan) to boundarys?

Hope everything is clear.
Tobi :/

Hi Tobias, did you find solution to convert faceZones to boundaries? If yes, how did you do that?
