Detailed Description

template<class ContextType>
struct AMDiS::ContextGeometry< ContextType >

Wrapper class for element and geometry.

A LocalContext can be either a grid entity of codim 0 (called an element) or an intersection of elements. The element and its geometry may be stored externally and can be passed along with the localContext object. Since an intersection has a geometry (and localGeometry) different from the geometry (and localGeometry) of the entity it belongs to, these objects are provided as well.

Template Parameters

LC	LocalContext, either element or intersection

Member Function Documentation

coordinateInElement()

auto coordinateInElement ( LocalCoordinate const &  p ) const

inline

Coordinate p given in coordinates inside the context, transformed to coordinate in geometry of the Element. NOTE: This is equivalent to geometryInElement.global(p)
