Detailed Description

This class provides functionality useful for implementation of ALE (Arbitrary Lagrangian-Eulerian) methods, in particular moving the boundary vertices of a mesh and then interpolating the new coordinates for the interior vertices accordingly.

Member Function Documentation

move() [1/4]

std::shared_ptr< MeshDisplacement > ALE::move ( std::shared_ptr< Mesh >  mesh, const BoundaryMesh &  new_boundary  )

static

Move coordinates of mesh according to new boundary coordinates. Works only for affine meshes.

Parameters

mesh	(Mesh) The affine mesh to move.
new_boundary	(BoundaryMesh) An affine mesh containing just the boundary cells.

Returns

MeshDisplacement Displacement encapsulated in Expression subclass MeshDisplacement.

move() [2/4]

std::shared_ptr< MeshDisplacement > ALE::move ( std::shared_ptr< Mesh >  mesh0, const Mesh &  mesh1  )

static

Move coordinates of mesh according to adjacent mesh with common global vertices. Works only for affine meshes.

Parameters

mesh0	(Mesh) The affine mesh to move.
mesh1	(Mesh) The affine mesh to be fit.

Returns

MeshDisplacement Displacement encapsulated in Expression subclass

move() [3/4]

void ALE::move ( Mesh &  mesh, const GenericFunction &  displacement  )

static

Move coordinates of mesh according to displacement function. This works only for affine meshes.

NOTE: This cannot be implemented for higher-order geometries as there is no way of constructing function space for position unless supplied as an argument.

Parameters

mesh	(Mesh) The affine mesh to move.
displacement	(GenericFunction) A vectorial generic function.

move() [4/4]

void ALE::move ( Mesh &  mesh, const Function &  displacement  )

static

Move coordinates of mesh according to displacement function.

Parameters

mesh	(Mesh) The mesh to move.
displacement	(Function) A vectorial Lagrange function of matching degree.
