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

pure 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.

void mfem::DeltaLFIntegrator::GetDeltaCenter ( Vector & center )

inline

Returns the center of the delta coefficient.

Definition at line 73 of file lininteg.hpp.

bool mfem::DeltaLFIntegrator::IsDelta ( ) const

inline

Returns true if the derived class instance uses a delta coefficient.
