  % function rb_sim_data = rb_reconstruction(this, detailed_data, rb_sim_data)
  % reconstructs a high dimensional solution trajectory from a reduced
  % solution trajectory.
  %
  % Parameters:
  %   detailed_data: of type TwoPhaseFlow.DetailedData
  %   rb_sim_data:   struct holding reduced simulation data returned by
  %                  ReducedModel.rb_simulation().
  %
  % Return values:
  %   rb_sim_data: struct holding the reduced simulation results and their
  %                reconstructions.
