Optimizing a function using sobol

[Mr. Xiaosong Zhang 0]

Hello guys,

 

I am working on an optimization of a motion function of a variable pitch turbine. The design variables in sobol can only be a number but not expressions. Is there any other way to optimize a function or expression?  Thank you.

You can control the functions by design variables, i.e. the parameters of the function.

Cheers

Here is an example:

 

The design variable x is the one you vary in the design engine. The parameter "function" can contain any kind of expression, and also additional design variables, of course.

Thanks for your reply. As your example, this makes "x" into the design variable. Is it any way to make each value of the function into design variable? Cheers.

Select the value for which you need a design variable > context menu (right mouse button) > create design variable. Alternatively, create a design variable from the menu and drag&drop it to the location in the expression.
