You have to choose variables to be optimized as well as the range you will allow for these variables.

Sorry, I have the same problem. But I dont know, where I can choose the variables. Can you halp me? Thanks

Double click on part, select 'Optimization', tick 'Include', set your nominal/min/max values. Click OK
