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

Create uniformly refined mesh

Arguments

mesh (Mesh)

The mesh to refine.

redistribute (_bool_)

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

Returns

Mesh

The refined mesh.

Example

mesh = refine(mesh);

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)

Create uniformly refined mesh

Arguments

refined_mesh (Mesh)

The mesh that will be the refined mesh.

mesh (Mesh)

The original mesh.

redistribute (_bool_)

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

Arguments

mesh (Mesh)

The mesh to refine.

cell_markers (MeshFunction <bool>)

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

redistribute (_bool_)

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

Returns

Mesh

The locally refined mesh.

Example

CellFunction<bool> cell_markers(mesh);
cell_markers.set_all(false);
Point origin(0.0, 0.0, 0.0);
for (CellIterator cell(mesh); !cell.end(); ++cell)
{
    Point p = cell->midpoint();
    if (p.distance(origin) < 0.1)
        cell_markers[*cell] = true;
}
mesh = refine(mesh, cell_markers);

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

Create locally refined mesh

Arguments

refined_mesh (Mesh)

The mesh that will be the refined mesh.

mesh (Mesh)

The original mesh.

cell_markers (MeshFunction <bool>)

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

redistribute (_bool_)

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