! Purpose: LES inter processor communication. 
!
! Description: none.
!
! Input: regions = data of all regions
!        iReg    = current region number
!
! Output: global% = new global parameters after global communication
!
! Notes: This procedure is always done regardless turbulence model selected.
!        The input/output global variables are always defined. 
!        If not needed, the result is simply not used.
