Detailed Description

template<int dim, int nstate>
class PHiLiP::ROLObjectiveSimOpt< dim, nstate >

Interface between the ROL::Objective_SimOpt PHiLiP::Functional.

Uses FFD to parametrize the geometry. An update on the simulation variables updates the DGBase object within the Functional and an update on the control variables updates the FreeFormDeformation object, which in turn, updates the DGBase.HighOrderGrid.volume_nodes.
