Member Function Documentation

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

virtual

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::BilinearFormIntegrator.

Definition at line 1053 of file bilininteg_divergence.cpp.

void mfem::VectorDivergenceIntegrator::AddMultTransposePA	(	const Vector &	x,
		Vector &	y
	)		const

virtual

Method for partially assembled transposed action.

Perform the transpose 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.

		DenseMatrix &	elmat
	)

virtual

Compute the local matrix representation of a bilinear form a(u,v) defined on different trial (given by u) and test (given by v) spaces. The rows in the local matrix correspond to the test dofs and the columns – to the trial dofs.

Reimplemented from mfem::BilinearFormIntegrator.

Used with BilinearFormIntegrators that have different spaces.
