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.

[inherited]

Attach ElemAssembly object for the right-hand side (both interior and boundary assembly).

virtual void libMesh::RBAssemblyExpansion::attach_output_assembly

[virtual, inherited]

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.
