! Purpose: receive and distribute the deformations of surfaces
!          in block-wise manner.
!
! Description: none.
!
! Input: regions = data of all grid regions.
!
! Output: regions%levels%grid%xyz = deformations at the boundaries
!         someMoved               = parts of grid moved.
!
! Notes: grid%xyz temporarily stores nodal displacements. The deformation
!        is applied to the finest grid first.
