Detailed Description

template<int dim, int spacedim = dim, typename VectorType = Vector<double>>
struct parallel::distributed::CellDataTransfer< dim, spacedim, VectorType >::CoarseningStrategies

When data is transferred during coarsening, it is not trivial to decide how to handle data of child cells which will be coarsened. Or in other words, which data should be stored in the corresponding parent cell.

In this namespace, we offer a few strategies that cope with this problem. Such strategies can be passed to the parallel::distributed::CellDataTransfer constructor.

check_equality()

template<int dim, int spacedim = dim, typename VectorType = Vector<double>>

static VectorType::value_type parallel::distributed::CellDataTransfer< dim, spacedim, VectorType >::CoarseningStrategies::check_equality ( const typename parallel::distributed::Triangulation< dim, spacedim >::cell_iterator &  parent, const VectorType &  input_vector  )

inlinestatic

Evaluate data from input_vector on children of parent. Check if data on all children match, and return that value.
