CFD Online Discussion Forums - [Other] internalFaces to patches ?? faceZones

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"...

Code:

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

Code:

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 :/
