Detailed Description

template<int dim>
class aspect::MeshDeformation::Interface< dim >

A base class for mesh deformation plugins. Each derived class should implement a function that determines the deformation velocity for certain mesh vertices and store them in a AffineConstraints<double> object. The velocities for all non-constrained vertices will be computed by solving a Laplace problem with the given constraints.

Member Function Documentation

needs_surface_stabilization()

template<int dim>

virtual bool aspect::MeshDeformation::Interface< dim >::needs_surface_stabilization ( ) const

virtual

A function that will be called to check whether stabilization is needed.

Reimplemented in aspect::MeshDeformation::Diffusion< dim >, aspect::MeshDeformation::FreeSurface< dim >, aspect::MeshDeformation::AsciiData< dim >, and aspect::MeshDeformation::BoundaryFunction< dim >.

compute_initial_deformation_on_boundary()

template<int dim>

virtual Tensor<1,dim> aspect::MeshDeformation::Interface< dim >::compute_initial_deformation_on_boundary ( const types::boundary_id  boundary_indicator, const Point< dim > &  position  ) const

virtual

A function that returns the initial deformation of points on the boundary (e.g. the surface vertices). position is the undeformed position and this function is expected to return the displacement vector of this position. The default implementation returns a zero displacement (= no initial deformation).

Reimplemented in aspect::MeshDeformation::AsciiData< dim >.

compute_initial_deformation_as_constraints()

template<int dim>

virtual void aspect::MeshDeformation::Interface< dim >::compute_initial_deformation_as_constraints ( const Mapping< dim > &  mapping, const DoFHandler< dim > &  mesh_deformation_dof_handler, const types::boundary_id  boundary_indicator, AffineConstraints< double > &  constraints  ) const

virtual

A function that creates constraints for the initial deformation of the mesh.

This function gives an alternative way to determine the initial deformation instead of using the compute_initial_deformation_on_boundary function. The default implementation of this function calls compute_initial_deformation_on_boundary() with the coordinates of each point on the boundary. If you need lower level control over the initial deformation or it is more efficient to provide constraints directly, override this function.

Reimplemented in aspect::MeshDeformation::Landlab< dim >.

compute_velocity_constraints_on_boundary()

template<int dim>

virtual void aspect::MeshDeformation::Interface< dim >::compute_velocity_constraints_on_boundary ( const DoFHandler< dim > &  mesh_deformation_dof_handler, AffineConstraints< double > &  mesh_velocity_constraints, const std::set< types::boundary_id > &  boundary_ids  ) const

virtual

A function that creates constraints for the velocity of certain mesh vertices (e.g. the surface vertices) for a specific set of boundaries. The calling class will respect these constraints when computing the new vertex positions. The default implementation creates no constraints.

Reimplemented in aspect::MeshDeformation::ParallelUnstructuredInterface< dim >, aspect::MeshDeformation::Diffusion< dim >, aspect::MeshDeformation::FreeSurface< dim >, and aspect::MeshDeformation::BoundaryFunction< dim >.

boundary_composition()

template<int dim>

virtual double aspect::MeshDeformation::Interface< dim >::boundary_composition ( const types::boundary_id  boundary_indicator, const Point< dim > &  position, const unsigned int  compositional_field  ) const

virtual

Return the composition that is to hold at a particular position on the boundary of the domain.

Parameters

boundary_indicator	The boundary indicator of the part of the boundary of the domain on which the point is located at which we are requesting the composition.
position	The position of the point at which we ask for the composition.
compositional_field	The index of the compositional field between 0 and parameters.n_compositional_fields.

Returns

Boundary value of the compositional field compositional_field at the position position.
