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.[in] | p | A ParameterList of the form <ParameterList>

void panzer::Integrator_BasisTimesScalar< EvalT, Traits >::postRegistrationSetup | ( | typename Traits::SetupData | sd, |
PHX::FieldManager< Traits > & | fm | ||
) |
Post-Registration Setup.
Get the Kokkos::Views of the field multipliers, and determine the index in the Workset bases for our particular basis name.
[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 unused, though part of the interface. |

void panzer::Integrator_BasisTimesScalar< EvalT, Traits >::evaluateFields | ( | typename Traits::EvalData | workset | ) |
Evaluate Fields.
This actually performs the integration by calling operator()()
in a Kokkos::parallel_for
over the cells in the Workset
.
[in] | workset | The Workset on which you're going to do the integration. |
Definition at line 265 of file Panzer_Integrator_BasisTimesScalar_impl.hpp.
void panzer::Integrator_BasisTimesScalar< EvalT, Traits >::operator() | ( | const FieldMultTag< NUM_FIELD_MULT > & | tag, |
const std::size_t & | cell | ||
) | const |
Perform the integration.
Generally speaking, for a given cell in the Workset
, this routine loops over quadrature points and bases to perform the integration, scaling the vector field to be integrated by the multiplier ( ) and any field multipliers ( , , etc.).
[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. |

Constructor can do some validation of the input ParameterList
