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

Construct a ParGridFunction corresponding to *pf and the data from *gf which is a local GridFunction on each processor.

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

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

ParGridFunction::ParGridFunction	(	ParMesh *	pmesh,
		GridFunction *	gf
	)

Construct a ParGridFunction from the given serial GridFunction. The data from 'gf' is NOT copied.
