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]	evalStyle	An `enum` declaring the behavior of this `Evaluator`, which is to either: compute and contribute (`CONTRIBUTES`), or compute and store (`EVALUATES`).
[in]	resName	The name of either the contributed or evaluated field, depending on `evalStyle`.
[in]	fluxName	The name of the vector-valued function being integrated ( $\vec{s}$ ).
[in]	basis	The basis that you'd like to use ( $\phi$ ).
[in]	ir	The integration rule that you'd like to use.
[in]	multiplier	The scalar multiplier out in front of the integral you're computing ( ). If not specified, this defaults to 1.
[in]	fmNames	A list of names of fields that are multipliers out in front of the integral you're computing ( , , etc.). If not specified, this defaults to an empty `vector`.
[in]	vecDL	The 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_argument	If any of the inputs are invalid.
std::logic_error	If 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]

p

A 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 ( ), and
"Field Multipliers" is an optional list of names of fields that are multipliers out in front of the integral you're computing ( , , etc.).
"Vector Data Layout" is the vector data layout that you'd like to use.

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 Kokkos::View versions of the field multiplier, if there are any.

Parameters

[in]	sd	Essentially a list of `Workset`s, which are collections of cells (elements) that all live on a single process.
[in]	fm	This is an unused part of the `Evaluator` interface.

Definition at line 188 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] workset The Workset on which you're going to do the integration.

Definition at line 410 of file Panzer_Integrator_GradBasisDotVector_impl.hpp.

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]	tag	An indication of the number of field multipliers we have; either 0, 1, or something else.
[in]	cell	The cell in the `Workset` over which to integrate.

	)		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.
