Detailed Description

template<int dim, typename VectorType = Vector<double>, int spacedim = dim>
class MappingQEulerian< dim, VectorType, spacedim >::MappingQEulerianGeneric

A class derived from MappingQGeneric that provides the generic mapping with support points on boundary objects so that the corresponding Q3 mapping ends up being C1.

Definition at line 193 of file mapping_q_eulerian.h.

template<int dim, class VectorType , int spacedim>
MappingQEulerian< dim, VectorType, spacedim >::MappingQEulerianGeneric::MappingQEulerianGeneric ( const unsigned int  degree,
const MappingQEulerian< dim, VectorType, spacedim > &  mapping_q_eulerian 
)

Member Function Documentation

◆ get_vertices()

template<int dim, class VectorType , int spacedim>
std::array< Point< spacedim >, GeometryInfo< dim >::vertices_per_cell > MappingQEulerian< dim, VectorType, spacedim >::MappingQEulerianGeneric::get_vertices ( const typename Triangulation< dim, spacedim >::cell_iterator &  cell) const
overridevirtual

Return the mapped vertices of the cell. For the current class, this function does not use the support points from the geometry of the current cell but instead evaluates an externally given displacement field in addition to the geometry of the cell.

Reimplemented from Mapping< dim, dim >.

Definition at line 146 of file mapping_q_eulerian.cc.

◆ compute_mapping_support_points()

template<int dim, class VectorType , int spacedim>
std::vector< Point< spacedim > > MappingQEulerian< dim, VectorType, spacedim >::MappingQEulerianGeneric::compute_mapping_support_points ( const typename Triangulation< dim, spacedim >::cell_iterator &  cell) const
overridevirtual

Compute the positions of the support points in the current configuration. See the documentation of MappingQGeneric::compute_mapping_support_points() for more information.

Reimplemented from MappingQGeneric< dim, spacedim >.

Definition at line 167 of file mapping_q_eulerian.cc.

◆ preserves_vertex_locations()

template<int dim, class VectorType , int spacedim>
bool MappingQEulerian< dim, VectorType, spacedim >::MappingQEulerianGeneric::preserves_vertex_locations
overridevirtual

Always return false because MappingQEulerianGeneric does not in general preserve vertex locations (unless the translation vector happens to provide for zero displacements at vertex locations).

Reimplemented from MappingQGeneric< dim, spacedim >.

Definition at line 157 of file mapping_q_eulerian.cc.

Member Data Documentation

◆ mapping_q_eulerian

template<int dim, typename VectorType = Vector<double>, int spacedim = dim>
const MappingQEulerian<dim, VectorType, spacedim>& MappingQEulerian< dim, VectorType, spacedim >::MappingQEulerianGeneric::mapping_q_eulerian
private

Reference to the surrounding object off of which we live.

Definition at line 235 of file mapping_q_eulerian.h.

◆ support_quadrature

template<int dim, typename VectorType = Vector<double>, int spacedim = dim>
const SupportQuadrature MappingQEulerian< dim, VectorType, spacedim >::MappingQEulerianGeneric::support_quadrature
private

A member variable holding the quadrature points in the right order.

Definition at line 254 of file mapping_q_eulerian.h.

◆ fe_values

template<int dim, typename VectorType = Vector<double>, int spacedim = dim>
FEValues<dim, spacedim> MappingQEulerian< dim, VectorType, spacedim >::MappingQEulerianGeneric::fe_values
mutableprivate

FEValues object used to query the given finite element field at the support points in the reference configuration.

The variable is marked as mutable since we have to call FEValues::reinit from compute_mapping_support_points, a function that is 'const'.

Definition at line 264 of file mapping_q_eulerian.h.

◆ fe_values_mutex

template<int dim, typename VectorType = Vector<double>, int spacedim = dim>
Threads::Mutex MappingQEulerian< dim, VectorType, spacedim >::MappingQEulerianGeneric::fe_values_mutex
mutableprivate

A variable to guard access to the fe_values variable.
