Detailed Description

Class for integrating the bilinear form \(a(u,v) := (Q \nabla u, v)\) in either 2D or 3D and where \(Q\) is an optional coefficient (of type scalar, matrix, or diagonal matrix) \(u\) is in \(H^1\) and \(v\) is in \(H(curl\) or \(H(div)\). Partial assembly (PA) is supported but could be further optimized by using more efficient threading and shared memory.

◆ AddMultPA()

virtual void mfem::MixedVectorGradientIntegrator::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::MixedVectorGradientIntegrator::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)

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.
