Detailed Description

This class is used to assemble the skew-symmetric form of the nonlinear term arising in the Navier-Stokes equations \(.5*(u \cdot \nabla v, w ) - .5*(u \cdot \nabla w, v )\). Partial assembly is not supported; use VectorConvectionNLFIntegrator.

◆ AddMultGradPA()

void mfem::SkewSymmetricVectorConvectionNLFIntegrator::AddMultGradPA	(	const Vector &	x,
		Vector &	y ) const

overridevirtual

Method for partially assembled gradient action.

All arguments are E-vectors. This method can be called only after the method AssembleGradPA() has been called.

Parameters

[in]	x	The gradient Operator is applied to the Vector x.
[in,out]	y	The result Vector: \( y += G x \).

Reimplemented from mfem::NonlinearFormIntegrator.

◆ AddMultPA()

void mfem::SkewSymmetricVectorConvectionNLFIntegrator::AddMultPA	(	const Vector &	x,
		Vector &	y ) const

overridevirtual

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.

Reimplemented from mfem::NonlinearFormIntegrator.

		const Vector &	elfun,
		DenseMatrix &	elmat )

overridevirtual

Assemble the local gradient matrix.

◆ AssembleGradDiagonalPA()

void mfem::SkewSymmetricVectorConvectionNLFIntegrator::AssembleGradDiagonalPA ( Vector & diag ) const

overridevirtual

Method for computing the diagonal of the gradient with partial assembly.

The result Vector diag is an E-Vector. This method can be called only after the method AssembleGradPA() has been called.

Parameters

[in,out] diag The result Vector: \( diag += diag(G) \).

Reimplemented from mfem::NonlinearFormIntegrator.

		const FiniteElementSpace &	fes )

overridevirtual

Prepare the integrator for partial assembly (PA) gradient evaluations on the given FE space fes at the state x.

The result of the partial assembly is stored internally so that it can be used later in the methods AddMultGradPA() and AssembleGradDiagonalPA(). The state Vector x is an E-vector.

Reimplemented from mfem::NonlinearFormIntegrator.

◆ AssemblePA() [1/2]

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.
