Mesh refine(const Mesh &mesh, bool redistribute = true)

Create uniformly refined mesh

@param mesh (Mesh)

The mesh to refine.

@param redistribute (_bool_)

Optional argument to redistribute the refined mesh if mesh is a distributed mesh.

@return Mesh

The refined mesh.

@code{.cpp}

mesh = refine(mesh);

@endcode

std::shared_ptr<const MeshHierarchy> refine(const MeshHierarchy &hierarchy, const MeshFunction<bool> &markers)

Refine a MeshHierarchy

void refine(Mesh &refined_mesh, const Mesh &mesh, bool redistribute = true)

Optional argument to redistribute the refined mesh if mesh is a distributed mesh.

Mesh refine(const Mesh &mesh, const MeshFunction<bool> &cell_markers, bool redistribute = true)

Create locally refined mesh

@param mesh (Mesh)

The mesh to refine.

@param cell_markers (_MeshFunction<bool>_)

A mesh function over booleans specifying which cells that should be refined (and which should not).

@param redistribute (_bool_)

Optional argument to redistribute the refined mesh if mesh is a distributed mesh.

@return Mesh

The locally refined mesh.

@code{.cpp}

void p_refine(Mesh &refined_mesh, const Mesh &mesh)

Increase the polynomial order of the mesh from 1 to 2, i.e. add points at the Edge midpoints, to make a quadratic mesh.

Return a p_refined mesh Increase the polynomial order of the mesh from 1 to 2, i.e. add points at the Edge midpoints, to make a quadratic mesh.

@param mesh (Mesh)

The original linear mesh.

@return Mesh
