Detailed Description

Constructor & Destructor Documentation

mfem::ParMesh::ParMesh ( )

inlineprotected

Definition at line 31 of file pmesh.hpp.

mfem::ParMesh::ParMesh ( const ParNCMesh & pncmesh )

Create from a nonconforming mesh.

Definition at line 684 of file pmesh.cpp.

mfem::ParMesh::ParMesh	(	const ParMesh &	pmesh,
		bool	copy_nodes = `true`
	)

explicit

Copy constructor. Performs a deep copy of (almost) all data, so that the source mesh can be modified (e.g. deleted, refined) without affecting the new mesh. If 'copy_nodes' is false, use a shallow (pointer) copy for the nodes, if present.
