Hello everyone
I want to have parametric study of two variables each having different range of values.
How can I include such thing in a timedependent study?

Thanks in advance.
Siva

Hi

check the doc about the "Parametric Sweep" node, you add it manually before your time dependent series. Then check the doc again about how to best handle multiple parameters

Good luck

Thanks dr. Ivar.
I got from the doc.
Actually I wanted to use full multiparameter sweep (solve for the first value of the first parameter combined with all values of the second parameter, then the second value of the first parameter combined with all values of the second parameter, and so on).

This was not working properly with all the possible settings.

But actually an earlier parameteric setting was lying in the job configuration giving wrong combinations. I deleted the study, saved closed and added new study I got now without any problem

Thanks again.

Hi

read carefully the way the parameters are stacked, it's not 100% obvious the first time ;)
