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).

| aspect::internal::Assembly::CopyData::AdvectionSystem< dim >::AdvectionSystem | ( | const FiniteElement< dim > & | finite_element, |
| const bool | field_is_discontinuous | ||
| ) |
Constructor.
| finite_element | The element that describes the field for which we are trying to assemble a linear system. Not the global finite element. |
| field_is_discontinuous | If true, the field is a DG element. |
| 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 426 of file interface.h.
| 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. These arrays are of a length sufficient 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.

| 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 447 of file interface.h.
| 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 455 of file interface.h.
| 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)

| 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 array has a length sufficient to hold one element for each possible face and sub-face of the current cell. The object is not used and has size zero if in the continuous Galerkin case.
