Public Member Functions
	H1Space (Mesh *mesh=NULL, Shapeset *shapeset=NULL)
virtual	~H1Space ()
void	fix_vertex (int id, scalar value=0.0)
	Removes the degree of freedom from a vertex node with the given id (i.e., its number in the mesh file) and makes it part of the Dirichlet lift with the given value. This is a special-purpose function which normally should not be needed. It is intended for fixing the solution of a system which would otherwise be singular and for some reason a standard Dirichlet condition (with non-zero measure on the boundary) is not suitable.
virtual Space *	dup (Mesh *mesh) const
	Creates a copy of the space. For internal use (see RefSystem).
virtual int	get_type () const
	Internal. Return type of this space (H1 = 0, Hcurl = 1, Hdiv = 2, L2 = 3).

void H1Space::fix_vertex	(	int	id,

Removes the degree of freedom from a vertex node with the given id (i.e., its number in the mesh file) and makes it part of the Dirichlet lift with the given value. This is a special-purpose function which normally should not be needed. It is intended for fixing the solution of a system which would otherwise be singular and for some reason a standard Dirichlet condition (with non-zero measure on the boundary) is not suitable.
