arithmeticAverage()

template<typename T , typename Tresult >

Tresult Opm::utils::arithmeticAverage	(	const T &	t1,
		const T &	t2
	)

Computes the arithmetic average: a_A(t_1, t_2) = (t_1 + t_2)/2.

Referenced by Opm::EulerUpstreamResidualDetails::UpdateForCell< UpstreamSolver, PressureSolution >::operator()().

geometricAverage()

template<typename T >

T Opm::utils::geometricAverage	(	const T &	t1,
		const T &	t2
	)

Computes the geometric average: a_G(t_1, t_2) = \sqrt{t_1 t_2}. Since we use std::sqrt(), this function will only compile when T is convertible to and from double.

harmonicAverage()

template<typename T >

T Opm::utils::harmonicAverage	(	const T &	t1,
		const T &	t2
	)

Computes the harmonic average: a_H(t_1, t_2) = \frac{2}{1/t_1 + 1/t_2} = \frac{2 t_1 t_2}{t_1 + t_2}.
