Hello Ansys community,

I would like to know if it's possible to manually create design points for a parametric study, then:

In a loop, read the results of the manual design points, then utilize these results to create new design points? I want to apply a genetic algorithm, but I need to do it on the workbench level, as every parameter needs to run ACP-pre module for every design point.

Any help or nudge in the right direction is appreciated.

Best regards.

Hi

 

Not sure exactly what you want to do, but

 

Perhaps it might be possible to use workbench/act scripting to do something what you want.

All the best

Hello krall91, I think your description is still bit unclear. Will you please elaborate it more? Yes, As stated by Erik, it may be possible with workbench/act scripting. Thanks

Dear Erik & bhagwantP, thank you for your responses. As Eric suggested, I dabbled a bit in ansys workbench scripting.

In a loop, I can read the output of a design point, then automatically generate new design points, solve them, make new design points from the solutions etc. However, I have a couple minor inconveniences:

At the moment I can read data from only the current design point with this:

output = Parameters.GetParameter(Name="PX").Value.Value

with PX being whatever number my output parameter is. But this only works on the "current design point" where I set the current point with:

Parameters.SetBaseDesignPoint(DesignPoint=designPointX)

with designPointX being whatever design point I wish to read. I was wondering if it was possible to read the values of a design point by just entering the name of the design point, as you can do when you are writing the design points with something like:

designPointX.SetParameterExpression(Parameter=Parameters.GetParameter(Name="PY"), Expression="Z")?

since reading a design point value is not an action, I could not record it in the record journal to decipher it somehow.

 

And finally, when I run my loops, I get a frozen screen where nothing happens, and after a little while all the datapoints appear as solved. Is there a way for a script -during execution- to show these intermediate steps like design points with inputs shown but outputs are yet to be calculated?

I currently update my design points simply by the function UpdateAllDesignPoints().

Thank you for your time and follow-up.

Best regards.
