Detailed Description

This class encapsulates the CG1 representation of the displacement of a mesh as an Expression. This is particularly useful for the displacement returned by mesh smoothers which can subsequently be used in evaluating forms. The value rank is 1 and the value shape is equal to the geometric dimension of the mesh.
