Function Documentation

fill_copy_indices() [1/2]

template<int dim, int spacedim>

void internal::MGTransfer::fill_copy_indices	(	const DoFHandler< dim, spacedim > &	dof_handler,
		const MGConstrainedDoFs *	mg_constrained_dofs,
		std::vector< std::vector< std::pair< types::global_dof_index, types::global_dof_index > > > &	copy_indices,
		std::vector< std::vector< std::pair< types::global_dof_index, types::global_dof_index > > > &	copy_indices_global_mine,
		std::vector< std::vector< std::pair< types::global_dof_index, types::global_dof_index > > > &	copy_indices_level_mine,
		const bool	skip_interface_dofs = true
	)

Internal function for filling the copy indices from global to level indices

If skip_interface_dofs is false, the mapping will also contain DoFs at the interface between levels. This is desirable when transferring solution vectors instead of residuals.

compute_shift_within_children()

template<int dim>

unsigned int internal::MGTransfer::compute_shift_within_children	(	const unsigned int	child,
		const unsigned int	fe_shift_1d,
		const unsigned int	fe_degree
	)

Given the collection of child cells in lexicographic ordering as seen from the parent, this function computes the first index of the given child

setup_transfer() [1/2]

template<int dim, typename Number >

void internal::MGTransfer::setup_transfer	(	const DoFHandler< dim > &	dof_handler,
