Detailed Description

template<int dim>
class AppFrame::LocalIntegrator< dim >

The class using CellInfo and FaceInfo to compute local contributions to a 1form.

Objects of this class are handed to the function DoFApplication::integrate_1form(). Derived classes for instance compute local contributions to the residual.

In addition to the local integration functions cell(), bdry() and face(), objects of this class provide control information to the DoFApplication loop:

• cell_quadrature, bdry_quadrature and face_quadrature determine the quadrature rules used on cells, boundary and interior faces, respectively. A rule with zero points means that the loop over these entities should be skipped.

virtual

An optional function called after the integration loop.

template<int dim>

void AppFrame::LocalIntegrator< dim >::set_gauss_quadrature	(	unsigned int	n_cell_points,
		unsigned int	n_bdry_points,
		unsigned int	n_face_points
	)

Assign n-point Gauss quadratures to each of the quadrature rules.

Here, a size of zero points means that no loop over these grid entities should be performed.
