Constructor & Destructor Documentation

mfem::DomainLFIntegrator::DomainLFIntegrator	(	Coefficient &	QF,
		int	a = `2`,
		int	b = `0`
	)

inline

Constructs a domain integrator with a given Coefficient.

Definition at line 100 of file lininteg.hpp.

mfem::DomainLFIntegrator::DomainLFIntegrator	(	Coefficient &	QF,
		const IntegrationRule *	ir
	)

inline

Constructs a domain integrator with a given Coefficient.

Definition at line 106 of file lininteg.hpp.

void mfem::DomainLFIntegrator::AssembleDeltaElementVect	(	const FiniteElement &	fe,
		ElementTransformation &	Trans,
		Vector &	elvect
	)

virtual

Assemble the delta coefficient at the IntegrationPoint set in Trans which is assumed to map to the delta coefficient center.

Note: This method should be called for one mesh element only, including in parallel, even when the center of the delta coefficient is shared by multiple elements.

Definition at line 57 of file lininteg.cpp.

void mfem::DomainLFIntegrator::AssembleRHSElementVect	(	const FiniteElement &	el,
		ElementTransformation &	Tr,
		Vector &	elvect
	)

virtual

Given a particular Finite Element and a transformation (Tr) computes the element right hand side element vector, elvect.
