Member Function Documentation

void mfem::DomainLFGradIntegrator::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.

Implements mfem::DeltaLFIntegrator.

Definition at line 98 of file lininteg.cpp.

void mfem::DomainLFGradIntegrator::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.

Implements mfem::LinearFormIntegrator.
