OptParam: Doing parametrization by means of shapeopt. This class is the abstract interface of a parametrization method, ie. a map from the boundary controlpoints to the interior controlpoints. Most importantly this method is the main 'bookkeeper' in my code. One of the main members is 'm_mappers' which holds a vector with a gsDofMapper for each dimension. For each dimension this Dofmapper is a 'Degrees of Freedom Mapper' that maps local indicies to global indicies of the controlpoints. This also takes care of the coupling of interfaces and possible elimination/ fixation of the boundary controlpoints. Finally by tagging controlpoints we can flag the ones that has a special role later, e.g. the design variables of a shape optimixation step. For performing OptParam the tagged points denotes the boundary controlpoints that should end up in the configuration of the 'goal' (the shape we want to parametrize) When constructing the class the default behaivour is to glue the interfaces, fix and tag the controlpoints on the boundary. In the following methods when handling controlpoints we use the format. The important methods are. The base class for shape optimization problems. It inherits from the gsOptProblem<> from G+Smo which interfaces IpOpt.
