Detailed Description

template<int dim>
struct aspect::internal::Assembly::CopyData::AdvectionSystem< dim >

Additionally to the Stokes system the Advection system copy data object also needs to keep track of contributions across faces (mostly for discontinuous elements that contain DG terms).

Constructor & Destructor Documentation

§ AdvectionSystem() [1/2]

template<int dim>
aspect::internal::Assembly::CopyData::AdvectionSystem< dim >::AdvectionSystem ( const FiniteElement< dim > &  finite_element,
const bool  field_is_discontinuous 
)

Constructor.

Parameters
finite_elementThe element that describes the field for which we are trying to assemble a linear system. Not the global finite element.
field_is_discontinuousIf true, the field is a DG element.

§ AdvectionSystem() [2/2]

Copy constructor.

Member Data Documentation

§ local_matrix

template<int dim>
FullMatrix<double> aspect::internal::Assembly::CopyData::AdvectionSystem< dim >::local_matrix

Local contributions to the global matrix that correspond only to the variables listed in local_dof_indices

Definition at line 420 of file interface.h.

§ local_matrices_int_ext

template<int dim>
std::vector<FullMatrix<double> > aspect::internal::Assembly::CopyData::AdvectionSystem< dim >::local_matrices_int_ext

Local contributions to the global matrix from the face terms in the discontinuous Galerkin method. The vectors are of length GeometryInfo<dim>::max_children_per_face * GeometryInfo<dim>::faces_per_cell so as to hold one matrix for each possible face or subface of the cell. The discontinuous Galerkin bilinear form contains terms arising from internal (to the cell) values and external (to the cell) values. _int_ext and ext_int hold the terms arising from the pairing between a cell and its neighbor, while _ext_ext is the pairing of the neighbor's dofs with themselves. In the continuous Galerkin case, these are unused, and set to size zero.

Definition at line 432 of file interface.h.

§ local_matrices_ext_int

template<int dim>
std::vector<FullMatrix<double> > aspect::internal::Assembly::CopyData::AdvectionSystem< dim >::local_matrices_ext_int

Definition at line 433 of file interface.h.

§ local_matrices_ext_ext

template<int dim>
std::vector<FullMatrix<double> > aspect::internal::Assembly::CopyData::AdvectionSystem< dim >::local_matrices_ext_ext

Definition at line 434 of file interface.h.

§ local_rhs

template<int dim>
Vector<double> aspect::internal::Assembly::CopyData::AdvectionSystem< dim >::local_rhs

Local contributions to the right hand side that correspond only to the variables listed in local_dof_indices

Definition at line 440 of file interface.h.

§ assembled_matrices

template<int dim>
std::vector<bool> aspect::internal::Assembly::CopyData::AdvectionSystem< dim >::assembled_matrices

Denotes which face matrices have actually been assembled in the DG field assembly. Entries for matrices not used (for example, those corresponding to non-existent subfaces; or faces being assembled by the neighboring cell) are set to false.

Definition at line 447 of file interface.h.

§ local_dof_indices

template<int dim>
std::vector<types::global_dof_index> aspect::internal::Assembly::CopyData::AdvectionSystem< dim >::local_dof_indices

Indices of those degrees of freedom that actually correspond to the temperature or compositional field. since this structure is used to represent just contributions to the advection systems, there will be no contributions to other parts of the system and consequently, we do not need to list here indices that correspond to velocity or pressure degrees (or, in fact any other variable outside the block we are currently considering)

Definition at line 458 of file interface.h.

§ neighbor_dof_indices

template<int dim>
std::vector<std::vector<types::global_dof_index> > aspect::internal::Assembly::CopyData::AdvectionSystem< dim >::neighbor_dof_indices

Indices of the degrees of freedom corresponding to the temperature or composition field on all possible neighboring cells. This is used in the discontinuous Galerkin method. The outer std::vector has length GeometryInfo<dim>::max_children_per_face * GeometryInfo<dim>::faces_per_cell, and has size zero if in the continuous Galerkin case.
