Detailed Description

Abstract class for definition of finite element functions on the mesh. This should include

simple FE spaces using the same finite element on all mesh elements with the same dimension,
p-refined spaces using variable FE order,
XFEM with arbitrary shape functions on every element.

virtual MixedPtr<FiniteElement> DiscreteSpace::fe ( ) const

pure virtual

Return Mixed of finite element objects.

TODO: The function should be in foem fe(const ElementAccessor<3> &). But we do not in fact depend on the element accessor now. This is temporary solution, which would work only if its type is EqualOrderDiscreteSpace. Otherwise, the general way would require a new "element FE handler" that would manage FEValues for all FE types within a given DiscreteSpace.

Implemented in EqualOrderDiscreteSpace.
