Detailed Description

template<typename AS, template< typename, int, int > class RT, typename UserFunction = Impl::DefaultUserFunction>
requires (Concepts::FlatAssembler<AS> and Concepts::ResultType<RT>)
class Ikarus::ResultFunction< AS, RT, UserFunction >

Usage:

// Usage with Dune::Vtk::VtkWriter
auto resultFunction = Ikarus::makeResultVtkFunction<resType>(assembler);
vtkwriter.addPointData(resultFunction);
 
// Usage with the native Dune::VTKWriter
auto resultFunction = Ikarus::makeResultFunction<resType>(assembler);
vtkWriter.addVertexData(resultFunction);

Template Parameters

AS	underlying assembler (provides the finite elements and the requested results)
RT	requested result type
UserFunction	Type of the user-defined function for custom result evaluation (default is DefaultUserFunction)

Member Function Documentation

evaluate()

template<typename AS , template< typename, int, int > class RT, typename UserFunction = Impl::DefaultUserFunction>

double Ikarus::ResultFunction< AS, RT, UserFunction >::evaluate ( int  comp, const Entity &  e, const Dune::FieldVector< ctype, griddim > &  local  ) const

inlineoverride

This function is required by the Dune::VTKFunction interface.

Parameters

comp	Stress component index
e	Entity on which to evaluate the stress
local	Local coordinates within the entity

Returns

Stress component value

name()

template<typename AS , template< typename, int, int > class RT, typename UserFunction = Impl::DefaultUserFunction>

constexpr std::string Ikarus::ResultFunction< AS, RT, UserFunction >::name ( ) const

inlineconstexproverride

This function is required by the Dune::VTKFunction interface.

Returns

String representing the name of the result type

ncomps()

template<typename AS , template< typename, int, int > class RT, typename UserFunction = Impl::DefaultUserFunction>

int Ikarus::ResultFunction< AS, RT, UserFunction >::ncomps ( ) const

inlineoverride

This function is required by the Dune::VTKFunction interface.

Returns

Number of stress components

precision()

Dune::VTK::Precision Ikarus::ResultFunction< AS, RT, UserFunction >::precision ( ) const

inlineoverride

This function is part of the Dune::VTKFunction interface. This has no affect when the ResultFunction is used as part of a the dune-vtk module

Returns

Precision (i.e. float64 or float32)
