! 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 RaNS variables.
!
! Notes: none.

! RCS Revision history:
!
! $Log: TURB_floRansSendCornEdgeCells.F90,v $
! Revision 1.6  2009/08/26 12:28:53  mtcampbe
! Ported to Hera.   Fixed logical expression syntax errors.  Replaced all
! IF (logical_variable)  with IF (logical_variable .eqv. .true.) as
! consistent with the specification.  Also changed: IF( ASSOCIATED(expr) )
! to IF ( ASSOCIATED(expr) .eqv. .true. ).   Intel compilers produce code
! which silently fails for some mal-formed expressions, so these changes
! are a net which should ensure that they are evaluated as intended.
!
! Revision 1.5  2009/04/07 15:00:29  mtcampbe
