To start an optimisation analysis go to the Simulation screen and click on the Optimisation + UA/SA tab. Calculations are updated using the Update toolbar icon in the usual way. The data on the Optimisation Calculation Options dialog is used to provide options to control the optimisation analysis as well as outputs to help you to understand the progress being made as the calculations continue.
Note: It is necessary to run the base simulation with monthly/annual outputs before opening the Optimisation + UA/SA tab. The optimisation simulations will all be run using the base calculation and model options. So the simulation period and all other options used in the optimisation are the same as those defined on the Simulation calculation options dialog.
There are 2 tabs on the Dialog:
You can learn about the outputs generated on the graph on this dialog during the optimisation:
