Detailed Description

template<class Coordinates = CGCoordinates::O, template< class > class BaseFunction = CGFunctions::Lucy, class Fields = CGFields::StandardFields>
class TimeAveragedCG< Coordinates, BaseFunction, Fields >

Evaluates time-averaged continuum fields and writes the data into a stat file.

Evaluates statistical output that is averaged over all time steps in the time interval [timeMin_, timeMax_].

This class should only be used to evaluate steady (time-independent) fields. For time-dependent fields, see CG and TimeSmoothedCG.

The class is derived from CG, which already contains the basic functionality to obtain time-dependent statistics. This class then averages the field values over time, with a uniform weight given to all time steps.
