Where does the OptisLang Optimizer store its results?

  I am using optisLang via workbench to run some parametric optimization studies on heat exchanger designs. Currently I am interested in running some CFD validation of the optimization results but I cannot find where the design points are contained.
  I have set up a work flow where the parameters of the excel sheet (OptisLang medium) are connected to the geometry in order to automatically update it and run CFD. I see that I can select the design points individually on the pareto front and it will show me the parameter values. However, on the pareto front, I can select design ~#2000 but my design points in the parameter set only go up to ~#1300.
  Where would I be able to find the proposed designs of the optimizer to update my workflow to run some CFD validation?

  Hi Lucas,
  
  The multi-objective optimization is mostlikly done with the surrogate model (MOP) as Solver.
  Therefore no design directories or entries in the Parameterset will be created.
  During the set-up in the optimization wizard you can activate the automatic validation of a certain number of design points.
  Since you want to run some specific designs to can add a new sensitivity system to the scenary and import the desired Parameterset from the omdb result file as Start-Designs (please remember to deactivated the dynamic sampling to avoid unnesescary runs).
