Detailed Description

class serif::operators::backend::mfem::detail::VolumeFieldOperator< Field, Equation, Schema >

Retain accepted data while applying a single field coupling with reusable contraction scratch.

Constructor & Destructor Documentation

VolumeFieldOperator()

template<typename Field, VolumeEquation Equation, typename Schema>

serif::operators::backend::mfem::detail::VolumeFieldOperator< Field, Equation, Schema >::VolumeFieldOperator ( std::shared_ptr< const VolumeData< Equation, Schema > > data )

inlineexplicit

Borrowed discretization resources still follow the accepted volume result's validity contract.

Member Function Documentation

Mult()

template<typename Field, VolumeEquation Equation, typename Schema>

void serif::operators::backend::mfem::detail::VolumeFieldOperator< Field, Equation, Schema >::Mult ( const ::mfem::Vector & input, ::mfem::Vector & output ) const

inlineoverride

Apply selected field derivatives without evaluating zero geometry variations.

Note

Element results are computed concurrently, each into its own vector, then added into the residual one by one in the original element order, so every sum is unchanged.

MultTranspose()

template<typename Field, VolumeEquation Equation, typename Schema>

void serif::operators::backend::mfem::detail::VolumeFieldOperator< Field, Equation, Schema >::MultTranspose ( const ::mfem::Vector & input, ::mfem::Vector & output ) const

inlineoverride

Apply the exact coefficient transpose of the selected physical field coupling (concurrent elements, ordered sums, as Mult).

run_actions()

template<typename Field, VolumeEquation Equation, typename Schema>

void serif::operators::backend::mfem::detail::VolumeFieldOperator< Field, Equation, Schema >::run_actions ( ) const

inlineprivate

Run the collected element actions concurrently, each into its own result.
