Timing Interface
These functions are used to get timings from class internal computations. The values are stored in a user defined concepts::InOutParameters structure in different arrays (see setTimings). These arrays can be grouped into a table for easier postprocessing with concepts::ResultsTable table; table.addMap(concepts::ResultsTable::DOUBLE, "jacobian", output); table.addMap(concepts::ResultsTable::DOUBLE, "whole_sumfact", output); std::ofstream ofs("table.gnuplot"); ofs << std::setprecision(20); table.print<concepts::ResultsTable::GNUPLOT>(ofs);

Detailed Description

template<class F = Real>
class hp3D::Identity< F >

A function class to calculate element matrices for the mass matrix.

This class is equiped with an interface to get timings of internal computations if compiled accordingly (see bilinearForm.cc file), see setTimings() and timings().

Member Function Documentation

clone()

template<class F = Real>

virtual Identity * hp3D::Identity< F >::clone ( ) const

inlinevirtual

Virtual constructor. Returns a pointer to a copy of itself. The caller is responsible to destroy this copy.

Implements concepts::BilinearForm< F, G >.

Definition at line 129 of file bilinearForm.hh.

info()

template<class F = Real>

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

protectedvirtual

Returns information in an output stream.

Reimplemented from concepts::BilinearForm< F, G >.

operator()() [1/2]

template<class F , class G = typename Realtype<F>::type>

virtual void concepts::BilinearForm< F, G >::operator() ( const Element< G > &  elmX, const Element< G > &  elmY, ElementMatrix< F > &  em  ) const

pure virtualinherited

Evaluates the bilinear form for all shape functions on elmX and elmY and stores the result in the matrix em.

Postcondition

The returned matrix em has the correct size.

Parameters

elmX	Left element (test functions)
elmY	Right element (trial functions)
em	Return element matrix

Implemented in vectorial::BilinearForm< F, G >, concepts::BilinearFormLiCo< F, G >, concepts::BilinearFormContainer< F, G >, concepts::BilinearF_Sum< F, H, J, G >, and concepts::BilinearF_W< F, H, J, G >.

operator()() [2/2]

template<class F , class G = typename Realtype<F>::type>

virtual void concepts::BilinearForm< F, G >::operator() ( const Element< G > &  elmX, const Element< G > &  elmY, ElementMatrix< F > &  em, const ElementPair< G > &  ep  ) const

inlinevirtualinherited

Evaluates the bilinear form for all shape functions on elmX and elmY and stores the result in the matrix em. If this method is not reimplemented in a derived class, the default behaviour is to call the application operator without ep.

Postcondition

The returned matrix em has the correct size.

Parameters

elmX	Left element
elmY	Right element
em	Return element matrix
ep	Element pair holding more information on the pair elmX and elmY

Reimplemented in vectorial::BilinearForm< F, G >.

Definition at line 57 of file bilinearForm.hh.

setTimings()

template<class F = Real>

static void hp3D::Identity< F >::setTimings ( concepts::InOutParameters *  timings )

static

Sets the class to store the timing values in. Additionally, the timeCntr_ is reset to 0. This counter is used to fill in the values into the arrays listed below in subsequent calls. The following timings are taken and stored in timings:

• evaluation of the Jacobian in jacobian
• calling the sum fatorization subroutine in whole_sumfact
• symmetrizing the element matrix in symmetrize_em

timings()

template<class F = Real>

static bool hp3D::Identity< F >::timings ( )

static

Returns true if the class is able to do timings. The ability to do timings depends on a compiler switch in bilinearform.cc file.
