Function Documentation

◆ categorize_by_boundary_ids()

template<int dim, typename AdditionalData >
void MatrixFreeTools::categorize_by_boundary_ids ( const Triangulation< dim > & tria,
AdditionalData & additional_data )

Modify additional_data so that cells are categorized according to their boundary IDs, making face integrals in the case of cell-centric loop simpler.

◆ compute_diagonal() [1/4]

template<int dim, int fe_degree, int n_q_points_1d, int n_components, typename Number , typename VectorizedArrayType , typename VectorType >
void MatrixFreeTools::compute_diagonal ( const MatrixFree< dim, Number, VectorizedArrayType > & matrix_free,
VectorType & diagonal_global,
const std::function< void(FEEvaluation< dim, fe_degree, n_q_points_1d, n_components, Number, VectorizedArrayType > &)> & cell_operation,
const unsigned int dof_no = 0,
const unsigned int quad_no = 0,
const unsigned int first_selected_component = 0 )

Compute the diagonal of a linear operator (diagonal_global), given matrix_free and the local cell integral operation cell_operation. The vector is initialized to the right size in the function.

The parameters dof_no, quad_no, and first_selected_component are passed to the constructor of the FEEvaluation that is internally set up.

void(CLASS::* cell_operation )(FEEvaluation< dim, fe_degree, n_q_points_1d, n_components, Number, VectorizedArrayType > &) const,
const CLASS * owning_class,
const unsigned int dof_no = 0,
const unsigned int quad_no = 0,
const unsigned int first_selected_component = 0 )

Same as above but with a class and a function pointer.

const unsigned int dof_no = 0,
const unsigned int quad_no = 0,
const unsigned int first_selected_component = 0 )

Compute the diagonal of a linear operator (diagonal_global), given matrix_free and the local cell integral operation cell_operation, interior face integral operation face_operation, and boundary face integral operation boundary_operation. The vector is initialized to the right size in the function.

The parameters dof_no, quad_no, and first_selected_component are passed to the constructor of the FEEvaluation that is internally set up.
