Detailed Description

template<class POLY, int dim = POLY::dimension, int spacedim = dim>
class FE_Poly< POLY, dim, spacedim >

This class gives a unified framework for the implementation of FiniteElement classes based on polynomial spaces like the TensorProductPolynomials or PolynomialSpace classes.

Every class conforming to the following interface can be used as template parameter POLY.

static const unsigned int dimension;
double compute_value (const unsigned int i,
const Point<dim> &p) const;
Tensor<1,dim> compute_grad (const unsigned int i,
const Point<dim> &p) const;
Tensor<2,dim> compute_grad_grad (const unsigned int i,
const Point<dim> &p) const;

Example classes are TensorProductPolynomials, PolynomialSpace or PolynomialsP.

This class is not a fully implemented FiniteElement class. Instead there are several pure virtual functions declared in the FiniteElement and FiniteElement classes which cannot implemented by this class but are left for implementation in derived classes.

Furthermore, this class assumes that shape functions of the FiniteElement under consideration do not depend on the actual shape of the cells in real space, i.e. update_once() includes update_values. For FiniteElements whose shape functions depend on the cells in real space, the update_once() and update_each() functions must be overloaded.

Todo:
Since nearly all functions for spacedim != dim are specialized, this class needs cleaning up.

UpdateFlags FE_Poly< POLY, dim, spacedim >::update_once ( const UpdateFlags  flags) const
protectedvirtual

Determine the values that need to be computed on the unit cell to be able to compute all values required by flags.

For the purpuse of this function, refer to the documentation in FiniteElement.

This class assumes that shape functions of this FiniteElement do not depend on the actual shape of the cells in real space. Therefore, the effect in this element is as follows: if update_values is set in flags, copy it to the result. All other flags of the result are cleared, since everything else must be computed for each cell.

Implements FiniteElement< dim, spacedim >.

Definition at line 129 of file fe_poly.templates.h.

template<class POLY , int dim, int spacedim>
UpdateFlags FE_Poly< POLY, dim, spacedim >::update_each ( const UpdateFlags  flags) const
protectedvirtual

Determine the values that need to be computed on every cell to be able to compute all values required by flags.

For the purpuse of this function, refer to the documentation in FiniteElement.

This class assumes that shape functions of this FiniteElement do not depend on the actual shape of the cells in real space.

The effect in this element is as follows:

  • if update_gradients is set, the result will contain update_gradients and update_covariant_transformation. The latter is required to transform the gradient on the unit cell to the real cell. Remark, that the action required by update_covariant_transformation is actually performed by the Mapping object used in conjunction with this finite element.

  • if update_hessians is set, the result will contain update_hessians and update_covariant_transformation. The rationale is the same as above and no higher derivatives of the transformation are required, since we use difference quotients for the actual computation.
