class MeshHierarchy

MeshHierarchy()

Constructor

explicit MeshHierarchy(std::shared_ptr<const Mesh> mesh)

Constructor with initial mesh

unsigned int size() const

Number of meshes

std::shared_ptr<const Mesh> operator[](int i) const

Get Mesh i, in range [0:size()] where 0 is the coarsest Mesh.

std::shared_ptr<const Mesh> finest() const

Get the finest mesh of the MeshHierarchy

std::shared_ptr<const Mesh> coarsest() const

Get the coarsest mesh of the MeshHierarchy

std::shared_ptr<const 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> unrefine() const

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

std::shared_ptr<const MeshHierarchy> coarsen(const MeshFunction<bool>& markers) const

Coarsen finest mesh by one level, based on markers (level n->n)

std::vector<std::size_t> 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.

std::shared_ptr<Mesh> rebalance() const

Rebalance across processes
