Detailed Description

Integrator for the DG form: alpha < rho_u (u.n) {v},[w] > + beta < rho_u |u.n| [v],[w] >, where v and w are the trial and test variables, respectively, and rho/u are given scalar/vector coefficients. The vector coefficient, u, is assumed to be continuous across the faces and when given the scalar coefficient, rho, is assumed to be discontinuous. The integrator uses the upwind value of rho, rho_u, which is value from the side into which the vector coefficient, u, points.

void mfem::DGTraceIntegrator::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.

void mfem::DGTraceIntegrator::AddMultTransposePA	(	const Vector &	x,

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.
