Detailed Description

Class for integrating (div u, p) where u is a vector field given by VectorFiniteElement through Piola transformation (for RT elements); p is scalar function given by FiniteElement through standard transformation. Here, u is the trial function and p is the test function. Note: the element matrix returned by AssembleElementMatrix2 does NOT depend on the ElementTransformation Trans.

)
inlinevirtual

Given a particular Finite Element computes the element matrix elmat.

Reimplemented from mfem::BilinearFormIntegrator.

void mfem::VectorFEDivergenceIntegrator::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.
