virtual void ParMesh::HexUniformRefinement ( ) [private, virtual]

Refine a hexahedral mesh.

Reimplemented from Mesh.

virtual void ParMesh::LocalRefinement	(	const Array< int > &	marked_el,
		int	type = `3`
	)		`[virtual]`

Refine the marked elements.

Reimplemented from Mesh.

virtual void ParMesh::NURBSUniformRefinement ( ) [private, virtual]

Refine NURBS mesh.

Reimplemented from Mesh.

virtual void ParMesh::Print ( ostream & out = cout ) const [virtual]

Print the part of the mesh in the calling processor adding the interface as boundary (for visualization purposes) using the default format.

Reimplemented from Mesh.

Referenced by main().

void ParMesh::PrintAsOne ( ostream & out = cout )

Write the mesh to the stream 'out' on Process 0 in a form suitable for visualization: the mesh is written as a disjoint mesh and the shared boundary is added to the actual boundary; both the element and boundary attributes are set to the precessor number.

void ParMesh::PrintAsOneXG ( ostream & out = cout )

Old mesh format (Netgen/Truegrid) version of 'PrintAsOne'.

void ParMesh::PrintInfo ( ostream & out = cout )

Print various parallel mesh stats.

virtual void ParMesh::PrintXG ( ostream & out = cout ) const [virtual]

Print the part of the mesh in the calling processor adding the interface as boundary (for visualization purposes) using Netgen/Truegrid format .

Reimplemented from Mesh.

virtual void ParMesh::QuadUniformRefinement ( ) [private, virtual]

Refine quadrilateral mesh.

Reimplemented from Mesh.
