Hi all,

I'm trying to mesh the following 3 regions.

I use the following createPatchDict to merge:

- fak12 with fak13
- wall_tubo with wall
- fak31 with fak32

    {
        // Name of new patch
        name tubo_inlet;

        // Dictionary to construct new patch from
        patchInfo
        {
            type patch;
   

         
        }

 
        constructFrom patches;

       
        patches (fak12 fak13);

        // If constructFrom = set : name of faceSet
      //  set f0;
    }
 
    {

        name tubo_asp;

      
        patchInfo
        {
            type patch;

        }

       constructFrom patches;

        patches (fak31 fak32);

     }


    {
        name wall_TUBO;
      
        patchInfo
        {
            type patch;

        }

       constructFrom patches;

        patches (wall wall_tubo1);

     }

);

// ************************************************************************* //

After I perform stitchMesh between fak21 & fak22.

Then I delete the patches with 0 faces from boundary file.

When I perform stitchMesh between fak11 and tubo_inlet I get the following:

Create time

Create mesh for time = 0

Coupling patches fak11 and tubo_inlet
Resulting (internal) faces will be in faceZone fak11tubo_inletCutFaceZone

Note: the overall area covered by both patches should be identical ("integral" interface).
If this is not the case use the -partial option



--> FOAM FATAL ERROR: 
Not all zones and patches needed in the definition have been found.  Please check your mesh definition.

    From function void slidingInterface::checkDefinition()
    in file slidingInterface/slidingInterface.C at line 85.

FOAM aborting

but in the boundary file definition I find the patches. So I can't understand the error..

Can someone help me please?

Thanks anyway.
