◆ AddMultPA()

virtual void mfem::MixedScalarCurlIntegrator::AddMultPA ( const Vector & x,
Vector & y ) const
protectedvirtual

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::MixedScalarCurlIntegrator::AddMultTransposePA ( const Vector & x,
Vector & y ) const
protectedvirtual

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.

◆ AssemblePA() [1/2]

void mfem::BilinearFormIntegrator::AssemblePA ( const FiniteElementSpace & fes)
protectedvirtual

Method defining partial assembly.

The result of the partial assembly is stored internally so that it can be used later in the methods AddMultPA() and AddMultTransposePA().

Reimplemented from mfem::BilinearFormIntegrator.
