! Purpose: send values to dummy cells of the corresponding patch
!          of the adjacent region which is on another processor.
!
! Description: none.
!
! Input: region    = current region
!        regionSrc = region to send data to
!        patch     = current patch of region.
!
! Output: patch%peul%SendBuff = send buffer.
!
! Notes: intended for conforming grid boundaries only.
