! Purpose: obtain deformation to boundary nodes from an external source.
!
! Description: none.
!
! Input: region     = grid dimensions and topology
!        boundMoved = flag for boundaries of region which have moved.
!
! Output: dNode = deformations at all six boundaries.
!
! Notes: variable dNode contains the whole 3-D field.
