◆ integrate()

template<class GridView , class FunctionType >

static auto FunctionIntegrator::integrate	(	const GridView &	gv,
		const FunctionType &	integrand,
		const int	quad_order
	)

inlinestatic

numerically integrates a given function

Numerically integrates the given integrand over the domain covered by the given GridView using a Dune::QuadratureRule of order quad_order on the grid specified by the GridView.

Template Parameters

GridView	the type of the GridView provided
FunctionType	the type of the function provided, needs to provide method `void evalall(...)` and the FunctionType's rangetype has to be RT

Parameters

gv	the GridView describing the domain of integration and the Grid for quadrature
integrand	the function to be integrated
quad_order	the order of the quadrature rule employed

◆ integrateDiscreteFunction()

template<class RangeType , class BasisType , class VectorType >

static auto FunctionIntegrator::integrateDiscreteFunction	(	const BasisType &	basis,
		const VectorType &	integrandCoeff,
		const int	quad_order
	)

inlinestatic

numerically integrates a gridfunction given by a coefficient vector

Numerically integrates the gridfunction represented by a coefficient vector in a given basis using a Dune::QuadratureRule of order quad_order.
