Detailed Description

Class for domain integrator \( L(v) := (f, \nabla v) \), where \( f = (f_{1x},f_{1y},f_{1z},\dots,f_{nx},f_{ny},f_{nz})\) and \(v=(v_1,\dots,v_n)\).

◆ AssembleDeltaElementVect()

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

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.

Implements mfem::DeltaLFIntegrator.
