Constructor & Destructor Documentation

hp1D::Space::Space	(	concepts::Mesh1 &	msh,
		uint	l,
		uint	p,
		concepts::BoundaryConditions *	bc = `0`
	)

Constructor.

Scans the mesh and sets the cells in the mesh active and the level of refinement and the polynomial degree in all cells to the given values. rebuild_ is set to true, ie. if the mesh is used it will firstly be rebuilt.

Parameters:

msh	The domain of interest partitioned into a mesh.
l	Level of refinement
p	Degree of the polynomials to be used.
bc	Boundary conditions
