◆ AddMultMF()

void mfem::VectorConvectionNLFIntegrator::AddMultMF	(	const Vector &	x,
		Vector &	y ) const

overridevirtual

Perform the action of integrator on the input x and add the result to the output y. Both x and y are E-vectors, i.e. they represent the element-wise discontinuous version of the FE space.

This method can be called only after the method AssembleMF() has been called.

Reimplemented from mfem::NonlinearFormIntegrator.

Method for partially assembled action.

Perform the action of integrator on the input x and add the result to the output y. Both x and y are E-vectors, i.e. they represent the element-wise discontinuous version of the FE space.

This method can be called only after the method AssemblePA() has been called.

◆ AssemblePA() [1/2]

void mfem::VectorConvectionNLFIntegrator::AssemblePA ( const FiniteElementSpace & fes )

overridevirtual

Method defining partial assembly.

The result of the partial assembly is stored internally so that it can be used later in the methods AddMultPA().

Definition at line 19 of file nonlininteg_vecconvection_pa.cpp.

◆ AssemblePA() [2/2]

void mfem::NonlinearFormIntegrator::AssemblePA	(	const FiniteElementSpace &	trial_fes,

virtual

The result of the partial assembly is stored internally so that it can be used later in the methods AddMultPA(). Used with BilinearFormIntegrators that have different spaces.

const IntegrationRule * mfem::VectorConvectionNLFIntegrator::GetDefaultIntegrationRule	(	const FiniteElement &	trial_fe,

		const ElementTransformation &	trans ) const

inlineoverrideprotectedvirtual

Subclasses should override to choose a default integration rule.

This method is intended to be overridden by subclasses to choose an appropriate integration rule based on the finite element spaces and/or element transformation. The trial_fe and test_fe should be equal for linear forms. The default base-class implementation returns null, which assumes that an appropriate rule is provided by another means, or that null integration rules are handled appropriately by the caller.

Reimplemented from mfem::Integrator.
