Member Data Documentation

cell

template<unsigned int dim>

dealii::DoFHandler<dim>::active_cell_iterator VolumeHandlerDG< dim >::cell

protected

Actual DG cell.

Definition at line 58 of file volume_handler_DG.hpp.

fe_dg

template<unsigned int dim>

const std::unique_ptr<dealii::FE_SimplexDGP<dim> > VolumeHandlerDG< dim >::fe_dg

protected

Internal Lagrangian basis class.

This internal member permits to exploit useful already implemented operations. Polynomial order is always set to 1 because the class executes only geometric operations not related to the degrees of freedom.

Definition at line 64 of file volume_handler_DG.hpp.

fe_values

template<unsigned int dim>

std::unique_ptr<dealii::FEValues<dim> > VolumeHandlerDG< dim >::fe_values

protected

Internal FEM basis class.

This internal member permits to exploit useful already implemented operations. As for fe_dg, the polynomial order is always 1 because it is only needed for geometric operations not related to the degrees of freedom.

Definition at line 77 of file volume_handler_DG.hpp.

initialized

template<unsigned int dim>

bool VolumeHandlerDG< dim >::initialized = false

protected

A condition to inform if the class is initialized on an element or not.

Definition at line 80 of file volume_handler_DG.hpp.

mapping

template<unsigned int dim>

const std::unique_ptr<dealii::MappingFE<dim> > VolumeHandlerDG< dim >::mapping

protected

Mapping of the discretized space, needed for geometrical reference-to-actual operations.

Definition at line 68 of file volume_handler_DG.hpp.

n_quad_points_1D

template<unsigned int dim>

const unsigned int VolumeHandlerDG< dim >::n_quad_points_1D

protected

Number of quadrature points in one dimensional elements.

Default is polynomial degree + 2.

Definition at line 55 of file volume_handler_DG.hpp.

QGLpoints

template<unsigned int dim>

const QGaussLegendreSimplex<dim> VolumeHandlerDG< dim >::QGLpoints

protected

Quadrature formula for volume elements.
