! Purpose: send values to edge and corner cells of an adjacent region.
!
! Description: this is for the case if the other region is located
!              on a different processor.
!
! Input: regions = data of all regions
!        iReg    = current region.
!
! Output: new values of FLD radiation variables.
!
! Notes: none.
