Member Function Documentation

◆ AssembleElementMatrix()

void mfem::VectorFEMassIntegrator::AssembleElementMatrix ( const FiniteElement el,
ElementTransformation Trans,
DenseMatrix elmat 
)
virtual

Given a particular Finite Element computes the element matrix elmat.

Reimplemented from mfem::BilinearFormIntegrator.

Definition at line 1718 of file bilininteg.cpp.

◆ AssembleElementMatrix2()

void mfem::VectorFEMassIntegrator::AssembleElementMatrix2 ( const FiniteElement trial_fe,
const FiniteElement test_fe,
ElementTransformation Trans,
DenseMatrix elmat 
)
virtual

Compute the local matrix representation of a bilinear form a(u,v) defined on different trial (given by u) and test (given by v) spaces. The rows in the local matrix correspond to the test dofs and the columns – to the trial dofs.

Reimplemented from mfem::BilinearFormIntegrator.
