Description

template<class Scalar>
class Dumux::EmbeddedCoupling::EllipseIntegration< Scalar >

Helper class to integrate over an elliptic domain.

Note
This is mostly useful if the integral is known and the integral mass has to be locally distributed to some non-matching domain
The algorithm is based on evenly spaced area elements with rejection sampling. To improve the quality of the integral, increase the sample size.
The area integral of a constant function is exact See Koch et al. (2020) https://doi.org/10.1016/j.jcp.2020.109369

◆ EllipseIntegration()

template<class Scalar >
Dumux::EmbeddedCoupling::EllipseIntegration< Scalar >::EllipseIntegration ( const Scalar  relCharLength)
inlineexplicit

Constructor.

Parameters
relCharLengthcharacteristic relative integration length (real number between 0 and 1)
Note
half the characteristic length means 2*2=4 times more integration points
