◆ geometry()

Geometry Dune::Entity< cd, dim, GridImp, EntityImp >::geometry ( ) const

obtain geometric realization of the entity

Each entity provides an object of type Dune::Geometry< dimension-codimension, dimensionworld, ... > that represents the map from a reference element to world coordinates.

Note
Previously, the geometry was encapsulated in the entity object and a const reference was returned.
The returned geometry object is guaranteed to remain valid until the grid is modified (or deleted).

◆ subEntities()

Parameters
codimcodimension to obtain number of subentities for
Note
The codimension is specified with respect to the grid dimension.
Unless the geometry type is None, this method is redundant and the same information can be obtained from the corresponding reference element.

Second-level dispatch to select the correct reference element for a grid entity.

This function is the default implementation of the second-level reference element dispatch performed by Entity.

When referenceElement() is called with an Entity, it will forward the call to referenceElement<ctype, mydim>(const GeometryType&). This default implementation will do the right thing as long as your geometry is based on a standard Dune ReferenceElement. If it is not and you want to supply your own reference element implementation, provide an override of this function for your specific geometry implementation.
