! Purpose: copy gradients at the patch to the dummy points  
!          for physical boundary conditions
!
! Description: dummy gradients copied from interior
!
! Input: region  = data of current region
!        lbound  = patch boundary index
!        idir,jdir,kdir = patch direction
!        indBeg,indEnd,jndBeg,jndEnd,kndBeg,kndEnd = indices of patch nodes
!        iBegV, iEndV = begin and end var index
!        iBegG, iEndG = begin and end gradient index
!  
! Output: gradi, gradj, gradk = gradients at dummy faces of the current patch
!
! Notes: none.
