Hello everyone,


I am working in the creation of a domain with blockMesh to simulate a problem. This domain is quite simple, but i have not could reach a good result due to the defaultFaces.
The domain that i am trying to obtain is the following.
Dominio.png
This domain must fit in my geometry.
Geometria.png
However, when i create the blockMeshDict file and obtain the result that i am looking for, between the boundarys , appears four defaultFaces that are located into the geometry, and when i try to mesh the geometry with snappyHexMEsh, the geometry get cut by the defaultFaces and dont let it be meshed.

Can i get rid of the defayltFaces or disable them.
