Detailed Description

A Weighing is a class that allows to compute weighted averages of values associated to cells of a grid.

Weighings are used in interpolateGlobally and interpolateGloballyWeak to define reasonable FE coefficients whenever the data to be interpolated cannot be represented in the FE space, e.g. interpolating a discontinuous function in a space of continuous functions. The conflicting interpolation values at one and the same interpolation node are then averaged - the kind of averaging is specified by the Weighing.

Predefined weighings are InverseVolume, Volume, PlainAverage.
