Detailed Description

This class computes map from slave entity to master entity.

Member Function Documentation

compute_periodic_pairs()

std::map< unsigned int, std::pair< unsigned int, unsigned int > > PeriodicBoundaryComputation::compute_periodic_pairs ( const Mesh &  mesh, const SubDomain &  sub_domain, const std::size_t  dim  )

static

For entities of dimension dim, compute map from a slave entity on this process (local index) to its master entity (owning process, local index on owner). If a master entity is shared by processes, only one of the owning processes is returned.

masters_slaves()

MeshFunction< std::size_t > PeriodicBoundaryComputation::masters_slaves ( std::shared_ptr< const Mesh >  mesh, const SubDomain &  sub_domain, const std::size_t  dim  )

static

This function returns a MeshFunction which marks mesh entities of dimension dim according to:

2: slave entities
1: master entities
0: all other entities

It is useful for visualising and debugging the Expression::map function that is used to apply periodic boundary conditions.
