Detailed Description

The class MeshDomains stores the division of a Mesh into subdomains. For each topological dimension 0 <= d <= D, where D is the topological dimension of the Mesh, a set of integer markers are stored for a subset of the entities of dimension d, indicating for each entity in the subset the number of the subdomain. It should be noted that the subset does not need to contain all entities of any given dimension; entities not contained in the subset are "unmarked".

Member Function Documentation

std::size_t MeshDomains::get_marker ( std::size_t  entity_index,
std::size_t  dim 
) const

Get marker (entity index, marker value) of a given dimension d. Throws an error if marker does not exist.

std::map< std::size_t, std::size_t > & MeshDomains::markers ( std::size_t  dim)

Get subdomain markers for given dimension (shared pointer version)

const std::map< std::size_t, std::size_t > & MeshDomains::markers ( std::size_t  dim) const

Get subdomain markers for given dimension (const shared pointer version)

bool MeshDomains::set_marker ( std::pair< std::size_t, std::size_t >  marker,
std::size_t  dim 
)

Set marker (entity index, marker value) of a given dimension d. Returns true if a new key is inserted, false otherwise.
