inline

Definition at line 41 of file pgridfunc.hpp.

mfem::ParGridFunction::ParGridFunction	(	ParFiniteElementSpace *	pf,
		double *	data
	)

inline

Construct a ParGridFunction using previously allocated array data.

The ParGridFunction does not assume ownership of data which is assumed to be of size at least pf->GetVSize(). Similar to the GridFunction and Vector constructors for externally allocated array, the pointer data can be NULL. The data array can be replaced later using the method SetData().

Definition at line 50 of file pgridfunc.hpp.

mfem::ParGridFunction::ParGridFunction	(	ParFiniteElementSpace *	pf,
		GridFunction *	gf
	)

Construct a ParGridFunction using a GridFunction as external data.

The parallel space *pf and the space used by *gf should match. The data from *gf is used as the local data of the ParGridFunction on each processor. The ParGridFunction does not assume ownership of the data.

Definition at line 24 of file pgridfunc.cpp.

mfem::ParGridFunction::ParGridFunction	(	ParFiniteElementSpace *	pf,
		HypreParVector *	tv
	)

Creates grid function on (all) dofs from a given vector on the true dofs, i.e. P tv.

Definition at line 30 of file pgridfunc.cpp.

mfem::ParGridFunction::ParGridFunction	(	ParMesh *	pmesh,
		GridFunction *	gf,
		int *	partitioning = `NULL`
	)

Construct a ParGridFunction from the given serial GridFunction. If partitioning == NULL (default), the data from 'gf' is NOT copied.
