Constructor & Destructor Documentation

template<typename EvalT , typename Traits >
panzer::Integrator_GradBasisDotVector< EvalT, Traits >::Integrator_GradBasisDotVector ( const panzer::EvaluatorStyle &  evalStyle,
const std::string &  resName,
const std::string &  fluxName,
const panzer::BasisIRLayout &  basis,
const panzer::IntegrationRule &  ir,
const double &  multiplier = 1,
const std::vector< std::string > &  fmNames = std::vector<std::string>(),
const Teuchos::RCP< PHX::DataLayout > &  vecDL = Teuchos::null 
)

Main Constructor.

Creates an Evaluator to evaluate the integral

\[ Ma(x)b(x)\cdots\int\vec{s}(x)\cdot\nabla\phi(x)\,dx, \]

where $ M $ is some constant, $ a(x) $, $ b(x) $, etc., are some fields that depend on position, $ \vec{s} $ is some vector-valued function, and $ \phi $ is some basis.

Parameters
[in]evalStyleAn enum declaring the behavior of this Evaluator, which is to either:
  • compute and contribute (CONTRIBUTES), or
  • compute and store (EVALUATES).
[in]resNameThe name of either the contributed or evaluated field, depending on evalStyle.
[in]fluxNameThe name of the vector-valued function being integrated ( $ \vec{s} $).
[in]basisThe basis that you'd like to use ( $ \phi $).
[in]irThe integration rule that you'd like to use.
[in]multiplierThe scalar multiplier out in front of the integral you're computing ( $ M $). If not specified, this defaults to 1.
[in]fmNamesA list of names of fields that are multipliers out in front of the integral you're computing ( $ a(x) $, $ b(x) $, etc.). If not specified, this defaults to an empty vector.
[in]vecDLThe vector data layout that you'd like to use. If not specified, this defaults to Teuchos::null and the vector data layout from the given ir is used.
Exceptions
std::invalid_argumentIf any of the inputs are invalid.
std::logic_errorIf the basis supplied does not support the gradient operator, or if the dimension of the space exceeds the dimension of the vector data layout.

template<typename EvalT , typename Traits >
panzer::Integrator_GradBasisDotVector< EvalT, Traits >::Integrator_GradBasisDotVector ( const Teuchos::ParameterList &  p)

ParameterList Constructor.

Creates an Evaluator to evaluate the integral

\[ Ma(x)b(x)\cdots\int\vec{s}(x)\cdot\nabla\phi(x)\,dx, \]

where $ M $ is some constant, $ a(x) $, $ b(x) $, etc., are some fields that depend on position, $ \vec{s} $ is some vector-valued function, and $ \phi $ is some basis.

Note
This constructor exists to preserve the older way of creating an Evaluator with a ParameterList; however, it is strongly advised that you not use this ParameterList Constructor, but rather that you favor the main constructor with its compile-time argument checking instead.
Parameters
[in]pA ParameterList of the form
<ParameterList>
<Parameter name = "Residual Name" type = "std::string" value = (required) />
<Parameter name = "Flux Name" type = "std::string" value = (required) />
<Parameter name = "Basis" type = "RCP<panzer::BasisIRLayout>" value = (required) />
<Parameter name = "IR" type = "RCP<panzer::IntegrationRule>" value = (required) />
<Parameter name = "Multiplier" type = "double" value = (required) />
<Parameter name = "Field Multipliers" type = "RCP<const std::vector<std::string>>" value = null (default)/>
<Parameter name = "Vector Data Layout" type = "RCP<PHX::DataLayout>" value = null (default)/>
</ParameterList>
where
  • "Residual Name" is the name for the term this Evaluator is evaluating,
  • "Flux Name" is the name of the vector-valued function being integrated ( $ \vec{s} $),
  • "Basis" is the basis that you'd like to use ( $ \phi $),
  • "IR" is the integration rule that you'd like to use,
  • "Multiplier" is the scalar multiplier out in front of the integral you're computing ( $ M $), and
  • "Field Multipliers" is an optional list of names of fields that are multipliers out in front of the integral you're computing ( $ a(x) $, $ b(x) $, etc.).
  • "Vector Data Layout" is the vector data layout that you'd like to use.

Member Function Documentation

template<typename EvalT , typename Traits >
void panzer::Integrator_GradBasisDotVector< EvalT, Traits >::postRegistrationSetup ( typename Traits::SetupData  d,
PHX::FieldManager< Traits > &  fm 
)

Post-Registration Setup.

Sets the basis index, and gets the PHX::View versions of the field multiplier, if there are any.

Parameters
[in]sdEssentially a list of Worksets, which are collections of cells (elements) that all live on a single process.
[in]fmThis is an unused part of the Evaluator interface.

Definition at line 155 of file Panzer_Integrator_GradBasisDotVector_impl.hpp.

template<typename EvalT , typename Traits >
void panzer::Integrator_GradBasisDotVector< EvalT, Traits >::evaluateFields ( typename Traits::EvalData  d)

Evaluate Fields.

This actually performs the integration by calling operator()() in a Kokkos::parallel_for over the cells in the Workset.

Parameters
[in]worksetThe Workset on which you're going to do the integration.

Definition at line 329 of file Panzer_Integrator_GradBasisDotVector_impl.hpp.

template<typename EvalT , typename Traits >
template<int NUM_FIELD_MULT>
KOKKOS_INLINE_FUNCTION void panzer::Integrator_GradBasisDotVector< EvalT, Traits >::operator() ( const FieldMultTag< NUM_FIELD_MULT > &  tag,
const Kokkos::TeamPolicy< PHX::exec_space >::member_type &  team 
) const

Perform the integration.

Generally speaking, for a given cell in the Workset, this routine loops over quadrature points, vector dimensions, and bases to perform the integration, scaling the vector field to be integrated by the multiplier ( $ M $) and any field multipliers ( $ a(x) $, $ b(x) $, etc.).

Note
Optimizations are made for the cases in which we have no field multipliers or only a single one.
Parameters
[in]tagAn indication of the number of field multipliers we have; either 0, 1, or something else.
[in]cellThe cell in the Workset over which to integrate.

const Kokkos::TeamPolicy< PHX::exec_space >::member_type &  team 
) const

Perform the integration.

Generally speaking, for a given cell in the Workset, this routine loops over quadrature points, vector dimensions, and bases to perform the integration, scaling the vector field to be integrated by the multiplier ( $ M $) and any field multipliers ( $ a(x) $, $ b(x) $, etc.). Uses Shared memory.

Note
Optimizations are made for the cases in which we have no field multipliers or only a single one.
Parameters
[in]tagAn indication of the number of field multipliers we have; either 0, 1, or something else.
[in]cellThe cell in the Workset over which to integrate.

Teuchos::RCP< Teuchos::ParameterList > panzer::Integrator_GradBasisDotVector< EvalT, TRAITS >::getValidParameters ( ) const
private

Get Valid Parameters.

Get all the parameters that we support such that the ParameterList Constructor can do some validation of the input ParameterList.

Returns
A ParameterList with all the valid parameters (keys) in it. The values tied to those keys are meaningless default values.
