Non-conformal interface vreation with periodic boundaries
It is sometimes inevitable to merge two or more meshes with periodic boundaries and create non-conformal interfaces between them. For example, half-domain meshes for swirler, mixer, and chamber have rotational periodic boundaries in the upper and lower half, and their upstream and downstream boundaries should be connected as non-conformal interfaces.
By default, the non-conformal interface is not allowed with periodic boundaries on sides, but this can be done by setting one variable before making the grid-interfaces. Execute the followins commands before creating the non-conformal interfaces.
