Support for use in BilinearForm. Can be used only when appropriate.

Reimplemented from mfem::BilinearFormIntegrator.

void mfem::MixedScalarIntegrator::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.

Member Data Documentation

bool mfem::MixedScalarIntegrator::same_calc_shape
protected

This parameter can be set by derived methods to enable single shape evaluation in case CalcTestShape() and CalcTrialShape() return the same result if given the same FiniteElement. The default is false.
