Detailed Description

template<class GV, class GF>
class AMDiS::CoarsenedGridFunction< GV, GF >

A grid function defining data on a coarser entity level than it can be bound to.

This wrapper function allows to bind the wrapped grid function to elements on a finer grid than this grid function was defined on. It works by traversing from the refined element through the hierarchy until a coarser element is found that is in the entity-set of the bound grid function.

Template Parameters

GV	The GridView the wrapper is bound to
GF	A GridFunction that is bound to a coarser GridView

Constructor & Destructor Documentation

CoarsenedGridFunction()

CoarsenedGridFunction ( GV const &  gridView, GF const &  gridFct  )

inline

Constructor.

Stores the GridFunction by value. Use a reference wrapper if copying the GridFunction is an expensive operation!
