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.

Member Function Documentation

fe()

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.

n_edge_dofs()

virtual unsigned int DiscreteSpace::n_edge_dofs ( const Edge &  edge ) const

pure virtual

Number of dofs associated to edge.

Implemented in EqualOrderDiscreteSpace.

n_elem_dofs()

virtual unsigned int DiscreteSpace::n_elem_dofs ( const ElementAccessor< 3 > &  cell ) const

pure virtual

Number of dofs associated to element (not shared by adjacent elements).

Implemented in EqualOrderDiscreteSpace.

n_face_dofs()

template<unsigned int dim>

unsigned int DiscreteSpace::n_face_dofs ( unsigned int  face_id )

inline

Number of dofs associated to generalized n-face (node, line, triangle or tetrahedron).

Definition at line 55 of file discrete_space.hh.

n_node_dofs()

virtual unsigned int DiscreteSpace::n_node_dofs ( unsigned int  nid ) const

pure virtual

Number of dofs associated to node. nid is the node index in the mesh tree.

Implemented in EqualOrderDiscreteSpace.
