Detailed Description

template<class Basis, class Dummy = void>
struct Dune::BasisInterfaceSwitch< Basis, Dummy >

Switch for uniform treatment of local and global basis classes.

Template Parameters

Basis	Type of the basis to handle.
Dummy	Dummy parameter for enable_if. This must be left at the default value of void.

We don't provide any uniform access to the types and constants pertaining to the global domain. Providing this would require the Geometry as template parameter as well, and the user code can build them itself if it needs them with the help of the geometry. The omitted types are DomainGlobal and Jacobian, the omitted constant is dimDomainGlobal.

Note

The local interface is assumed if the constant Basis::Traits::dimDomain exists and has a value greater than 0.

Member Function Documentation

gradient()

template<class Basis , class Dummy = void>

template<typename Geometry >

static void Dune::BasisInterfaceSwitch< Basis, Dummy >::gradient ( const Basis &  basis, const Geometry &  geometry, const DomainLocal &  xl, std::vector< FieldMatrix< RangeField, 1, Geometry::coorddimension > > &  grad  )

inlinestatic

Compute global gradient for scalar valued bases.

Parameters

basis	The basis to get the derivatives from.
geometry	The geometry to use to transform the derivatives (for a local basis, unused in the case of a global basis).
xl	The local coordinates where to evaluate the gradient.
grad	The result (will be resized to the appropriate number of entries.

Note

This make sense only for a scalar valued basis.
