Member Function Documentation

assembly()

template<typename F >

virtual void hp3D::ZeroTangentialValue< F >::assembly ( const concepts::Element< F > &  e, concepts::TColumn< F > *&  t, uint &  n, uint &  j, uint  length  )

virtual

Returns the TColumns t for this constraint in element e. n contains the next free global index in the space of constraints.

When treating dof by dof constraints, n should be increased after the creation of the TColumn (which gets as global index the old value of n).

When treating global constraints such as a zero mean value, n should be increased only once and all local constraints have to give this index to idx in the constructor of the new TColumn.

A similar idea stands behind j: it counts the local constraints which have already been treated. It therefore has to be increased after treating a constraint. j can be taken as index for the created TColumn to fill in the correct entry.

Parameters

e	Element of the computational space
t	List of TColumns
n	Next free global index in the space of constraints. n is increased if a global constraint is hit for the first time.
j	Next free local index for the constraints in this element. j is increased accordingly when treating constraints in this element.
length	Length of TColumn

concepts::TColumn

Implements constraints::AnalyticalConstraint< F >.

clone()

template<typename F >

virtual constraints::AnalyticalConstraint< F > * hp3D::ZeroTangentialValue< F >::clone ( ) const

virtual

Creates clone of itself and returns it. This clone function implements a virtual constructor (cf. Stroustrup p. 424).

Implements constraints::AnalyticalConstraint< F >.

info()

template<typename F >

virtual std::ostream & hp3D::ZeroTangentialValue< F >::info ( std::ostream &  os ) const

protectedvirtual

Returns information in an output stream.

Reimplemented from concepts::OutputOperator.

lengthT()

template<typename F >

virtual void hp3D::ZeroTangentialValue< F >::lengthT ( const concepts::Element< F > &  e, uint &  length  )

virtual

Computes the length of the TColumn. This method decides if this constraint is active on element e and how many local equations it generates. This is added to length.

Implements constraints::AnalyticalConstraint< F >.

localMatrix()

template<typename F >

virtual void hp3D::ZeroTangentialValue< F >::localMatrix ( concepts::ElementMatrix< F > &  em, uint &  j, const constraints::Element< F > &  elm  ) const

virtual

Fills the entries in the local constraints matrix em.

Parameters

em	Local constraints matrix. Has to be filled. The rows correspond to local dofs, the columns correspond to the equations this constraints creates in this element.
j	Local number of the constraints. Everytime, when a active constraint on the element is treated, j has to be increased by the number of equations this constraint created.
elm	Element of the constraints space

Implements constraints::AnalyticalConstraint< F >.

localVector()

template<typename F >

virtual void hp3D::ZeroTangentialValue< F >::localVector ( concepts::ElementMatrix< F > &  em, uint &  j, const constraints::Element< F > &  elm  ) const

virtual

Fills the entries in the local constraints vector em. The parameters have the same meaning as in localMatrix.

Implements constraints::AnalyticalConstraint< F >.
