◆ VectorMassIntegrator() [1/5]

mfem::VectorMassIntegrator::VectorMassIntegrator ( )
inline

Construct an integrator with coefficient 1.0.

◆ AddMultMF()

void mfem::VectorMassIntegrator::AddMultMF ( const Vector x,
Vector y 
) const
virtual

Perform the action of integrator on the input x and add the result to the output y. Both x and y are E-vectors, i.e. they represent the element-wise discontinuous version of the FE space.

This method can be called only after the method AssembleMF() has been called.

Reimplemented from mfem::BilinearFormIntegrator.

virtual

Method for partially assembled action.

Perform the action of integrator on the input x and add the result to the output y. Both x and y are E-vectors, i.e. they represent the element-wise discontinuous version of the FE space.

This method can be called only after the method AssemblePA() has been called.
