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.
Parameters: MeshDisplacement & mesh_displacement (const) – (
MeshDisplacement) Object to be copied.
Extract subfunction In python available as MeshDisplacement.sub(i)
Parameters: std::size_t i (const) – (std::size_t) Index of subfunction. Return type: Function &
