Detailed Description

This extends RBAssemblyExpansion to provide an assembly expansion for the case of time-dependent PDEs. This just requires an extra set of ElemAssembly functors for the time-derivative term.

attach_output_assembly() [1/3]

virtual void libMesh::RBAssemblyExpansion::attach_output_assembly ( std::vector< std::unique_ptr< ElemAssembly >> &  output_assembly )

virtualinherited

Attach ElemAssembly object for an output (both interior and boundary assembly). In this case we pass in vector arguments to allow for Q_l > 1.

attach_output_assembly() [2/3]

virtual void libMesh::RBAssemblyExpansion::attach_output_assembly ( std::vector< ElemAssembly *>  output_assembly )

virtualinherited

Attach ElemAssembly object for an output (both interior and boundary assembly). In this case we pass in vector arguments to allow for Q_l > 1.

attach_output_assembly() [3/3]

virtual void libMesh::RBAssemblyExpansion::attach_output_assembly ( ElemAssembly *  output_assembly )

virtualinherited

Attach ElemAssembly object for an output (both interior and boundary assembly). This function provides simpler syntax in the case that Q_l = 1; we do not need to use a vector in this case.
