Detailed Description

template<int dim, typename VectorType, int spacedim = dim>
class parallel::distributed::experimental::FieldTransfer< dim, VectorType, spacedim >

This class is similar to SolutionTransfer but it supports the case where elements have been activated during refinement, i.e., FE_Nothing elements have been associated with a finite elements during refinement.

Constructor & Destructor Documentation

◆ FieldTransfer()

template<int dim, typename VectorType , int spacedim>
parallel::distributed::experimental::FieldTransfer< dim, VectorType, spacedim >::FieldTransfer ( const DoFHandler< dim, spacedim > & dof_handler)

Constructor.

Parameters
[in]dof_handlerThe DoFHandler on which all the operations will happen. This constructor must be called before the underlying Triangulation is coarsened/refined.

Definition at line 32 of file field_transfer.cc.

◆ prepare_for_coarsening_and_refinement()

template<int dim, typename VectorType , int spacedim>
void parallel::distributed::experimental::FieldTransfer< dim, VectorType, spacedim >::prepare_for_coarsening_and_refinement ( const VectorType & in,
const unsigned int fe_nothing_index )

Prepare the current object for coarsening and refinement.

Parameters
[in]inThe vector that will be interpolated
[in]fe_nothing_indexThe finite element index associated with FE_Nothing

Definition at line 132 of file field_transfer.cc.

◆ interpolate()

template<int dim, typename VectorType , int spacedim>
void parallel::distributed::experimental::FieldTransfer< dim, VectorType, spacedim >::interpolate ( const Number & new_value,
const AffineConstraints< Number > & affine_constraints,
VectorType & out )

Interpolate the data previously stored in this object before the mesh was refined or coarsened onto the current set of cells. new_value is the value associated to the new degrees of freedom that where created during the element activation. affine_constraints is the AffineConstraints after refinement.
