! Purpose: check that the number of cells inside the physical domain is
!          the same or larger than the number of dummy cells.
!
! Description: none.
!
! Input: regions%levels%grid = coordinates (physical cells) and dimensions
!
! Output: regions%levels%grid%xyz = coordinates (dummy cells)
!
! Notes: only region interfaces with continuous grid are treated here.
