Member Function Documentation

◆ AddMultPA()

virtual void mfem::VectorFEMassIntegrator::AddMultPA ( const Vector x,
Vector y 
) const
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.

Reimplemented from mfem::BilinearFormIntegrator.

◆ AddMultTransposePA()

virtual void mfem::VectorFEMassIntegrator::AddMultTransposePA ( const Vector x,
Vector y 
) const
virtual

Method for partially assembled transposed action.

Perform the transpose 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.

Reimplemented from mfem::BilinearFormIntegrator.
