CFD Online Discussion Forums - mapFields : internal edges

Dear Foamers,

I'm currently trying to launch a case from an non uniform field using the utility mapfield.

My geometries are not consistant so I have to define a mapFieldsDict wich contains the edges that are consistent (means that they are at the same places on the two geometries) and those that are not.

My problem is that my mesh is generated in gambit, then exported to .msh and then imported in openfoam thanks to the "fluentMeshToFoam" utility.
Here is the log of this utility :

Code:

Building boundary and internal patches.

Creating patch 0 for zone: 3 start: 1 end: 150 type: velocity-inlet name: interiorCutting

Creating patch 1 for zone: 4 start: 151 end: 250 type: velocity-inlet name: interiorMapField

Creating patch 2 for zone: 5 start: 251 end: 370 type: wall name: fixedWallsMapField

Creating patch 3 for zone: 6 start: 371 end: 630 type: wall name: fixedWalls

Creating patch 4 for zone: 7 start: 631 end: 680 type: pressure-outlet name: outlet

Creating patch 5 for zone: 8 start: 681 end: 730 type: velocity-inlet name: inlet

Creating patch 6 for zone: 10 start: 731 end: 19240 type: interior name: default-interior

Creating patch for front and back planes



Patch interiorCutting is internal to the mesh  and is not being added to the boundary.

Patch interiorMapField is internal to the mesh  and is not being added to the boundary.

Adding new patch fixedWallsMapField of type wall as patch 0

Adding new patch fixedWalls of type wall as patch 1

Adding new patch outlet of type patch as patch 2

Adding new patch inlet of type patch as patch 3

Patch default-interior is internal to the mesh  and is not being added to the boundary.

Adding new patch frontAndBackPlanes of type empty as patch 4

My problem is that, for example, the interiorCutting patch is said to be internal and so is not added BUT I NEED IT FOR MAPFIELDS. So I would like that openfoam sets it to "patch". If I remember well, in blockmesh "patch" states for an edge or a plane that doesn't affect the flow but can be used for geometry concerns.

How can I do that? Can someone help me?

Thanks a lot!
:)
