Decoupling between the ``background mesh`` and ``front mesh`` if there is no hole present [overset]
I'm sorry for reporting again about
overset but it happens that I'm running few tests nowadays.
The algorithm doesn't set any
interpolated cells on the background mesh when there is no
holes in the model.
This leads to complete decoupling between the
background mesh and
Steps to reproduce
Since there is not geometry needed, simple empty overlapping meshes of any type or shape can reproduce this issue.
In order to see the issue clearly, I would suggest selecting actuation disk on the
front mesh or the front and back together.
By inspecting the case in
paraview, you will not found any interpolated cells on the background mesh. Also, both velocity and pressure fields on the background mesh are disturbed by the disk (of course in case, the disk is selected from the front mesh cells only). Using
overSimpleFoam is enough to see this behavior.

If this feature is not supported, maybe just through a warning or fatal error would be enough for the user to understand the limitation of the method.
A solution for this issue could be by selecting few layers inwards around the
oversetPatch to ensure the coupling. Or just marking few cells in the background as a hole before adding the interpolation layers. Probably, it is more trick than that specially if the front mesh is moving.
