  4. Dymola Model

  5. Problem: After simulation in ModelCenter, reservoir levels remained constant Skips UpperRes.level_start within the dsin.txt.template file Wrapper File Tweak • Fix: • markAsBeginning “UpperRes.level” offset=1markAsBeginning “UpperRes.level” offset=-1variable: upperLevel double 1 2 units=“m”

  6. Making Parameters Variable in Dymola • Problem: • After simulation in Dymola, certain parameters were not able to be modified through the simulation interface • Fix: • Add upper level parameter • Kevin’s “hack” • Delete annotations

  7. Combining Two Time Independent Responses • Problem: • To optimize the overall system’s utility, pumpFlow values were needed from within the simulation, not at the end • Fix: • Modify Dymola model to record the maximum flow rate [m3/s] through the pump, so that this value is available to ModelCenter after the simulation completes

  8. Handling Design Variables that are also Uncertain Variables -0.06 -0.05 -0.04 -0.03 -0.02 -0.01 0 0.01

  9. Results Deterministic Optimization Uncertainty Optimization (100 Samples)

  10. Your design problem is never too simple It’s called a “beta” version for a reason Test, test, test your model; successful runs in Dymola (HW3) does not guarantee smooth sailing in ModelCenter (HW4) Elicitations are more intricate than what meets the eye Having one Windows capable “laptop” per group member would be nice in hindsight Conclusions
