! Purpose: set boundary conditions or exchange data between adjacent
!          regions being on same processor.
!
! Description: none.
!
! Input: regions = data of all regions
!        iReg    = index of current region.
!
! Output: regions(iReg)%levels%plag = updated values (aiv,arv,cv,dv,tv)
!                                     in destination region.
!
! Notes: Current support for conforming region interface only.
