Detailed Description

Experimental implementation of a list of Meshes as a hierarchy.

Member Function Documentation

std::shared_ptr< const MeshHierarchy > MeshHierarchy::refine

(

const MeshFunction< bool > &

markers

)

const

Refine finest mesh of existing hierarchy, creating a new hierarchy (level n -> n+1)

std::shared_ptr<const MeshHierarchy> dolfin::MeshHierarchy::unrefine ( ) const

inline

Unrefine by returning the previous MeshHierarchy (level n -> n-1) Returns NULL for a MeshHierarchy containing a single Mesh

std::vector< std::size_t > MeshHierarchy::weight

(

)

const

Calculate the number of cells on the finest Mesh which are descendents of each cell on the coarsest Mesh, returning a vector over the cells of the coarsest Mesh.
