Detailed Description

template<int mydim, int cdim, class Grid>
class Dune::GenericGeometry::Geometry< mydim, cdim, Grid >

generic implementation of a DUNE (global) geometry

Geometry inherits all its features from BasicGeometry. It only adds GlobalGeometryTraits< Grid > as Traits parameter to the template parameter list.

Template Parameters

mydim	Dimension of the entity
cdim	Dimension of the coordinate space
Grid	The grid this geometry will be used in

Member Typedef Documentation

Jacobian

typedef Mapping::JacobianInverseTransposed Dune::GenericGeometry::BasicGeometry< mydim, GlobalGeometryTraits< Grid > >::Jacobian

inherited

Type used for Jacobian matrices.

Note

This is not a FieldMatrix but a proxy type that can be assigned to a FieldMatrix.

JacobianTransposed

typedef Mapping::JacobianTransposed Dune::GenericGeometry::BasicGeometry< mydim, GlobalGeometryTraits< Grid > >::JacobianTransposed

inherited

Type used for Jacobian matrices.

Note

This is not a FieldMatrix but a proxy type that can be assigned to a FieldMatrix.

bool cast

Like a pointer, a BasicGeometry casts to true if and only if it is properly initialized. If a geometry casts to false, none of the interface methods may be called.
