unsigned int | face_idx [2] |
std::bitset< 3 > | orientation |
FullMatrix< double > | matrix |
Data type that provides all information necessary to create periodicity constraints and a periodic p4est forest with respect to two 'periodic' cell faces.
Definition at line 2646 of file grid_tools.h.
CellIterator GridTools::PeriodicFacePair< CellIterator >::cell[2] |
The cells associated with the two 'periodic' faces.
Definition at line 2651 of file grid_tools.h.
unsigned int GridTools::PeriodicFacePair< CellIterator >::face_idx[2] |
The local face indices (with respect to the specified cells) of the two 'periodic' faces.
Definition at line 2657 of file grid_tools.h.
std::bitset<3> GridTools::PeriodicFacePair< CellIterator >::orientation |
The relative orientation of the first face with respect to the second face as described in orthogonal_equality() and DoFTools::make_periodicity_constraints() (and stored as a bitset).
Definition at line 2664 of file grid_tools.h.
FullMatrix<double> GridTools::PeriodicFacePair< CellIterator >::matrix |
A dim
\times dim
rotation matrix that describes how vector valued DoFs of the first face should be modified prior to constraining to the DoFs of the second face.
The rotation matrix is used in DoFTools::make_periodicity_constraints() by applying the rotation to all vector valued blocks listed in the parameter first_vector_components
of the finite element space. For more details see DoFTools::make_periodicity_constraints() and the glossary glossary entry on periodic conditions.
