Detailed Description

Class for integrating the bilinear form a(u,v) := (Q u, v), where u=(u1,...,un) and v=(v1,...,vn); ui and vi are defined by scalar FE through standard transformation.

Definition at line 1825 of file bilininteg.hpp.

Constructor & Destructor Documentation

mfem::VectorMassIntegrator::VectorMassIntegrator ( )
inline

Construct an integrator with coefficient 1.0.

Definition at line 1841 of file bilininteg.hpp.

mfem::VectorMassIntegrator::VectorMassIntegrator ( Coefficient q,
int  qo = 0 
)
inline

Construct an integrator with scalar coefficient q. If possible, save memory by using a scalar integrator since the resulting matrix is block diagonal with the same diagonal block repeated.

Definition at line 1847 of file bilininteg.hpp.

mfem::VectorMassIntegrator::VectorMassIntegrator ( Coefficient q,
const IntegrationRule ir 
)
inline

Definition at line 1849 of file bilininteg.hpp.

mfem::VectorMassIntegrator::VectorMassIntegrator ( VectorCoefficient q,
int  qo = 0 
)
inline

Construct an integrator with diagonal coefficient q.

Definition at line 1853 of file bilininteg.hpp.

mfem::VectorMassIntegrator::VectorMassIntegrator ( MatrixCoefficient q,
int  qo = 0 
)
inline

Construct an integrator with matrix coefficient q.

Definition at line 1856 of file bilininteg.hpp.

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

Given a particular Finite Element computes the element matrix elmat.

Reimplemented from mfem::BilinearFormIntegrator.

void mfem::VectorMassIntegrator::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.
