I am working on a pump optimization case similar to the TCFD + CAESES webinar/tutorial:
In that case, they perform Sobol (global sensitivity) analysis followed by Tsearch (local analysis).
I have few questions about the second part since the tutorial does not show how to setup the Tsearch from the best Sobol result:
- does Tsearch engine determine the new upper and lower bounds for the design parameters automatically based on the Sobol analysis;
- or do I set the bounds manually?
- If manually, is there a rule-of-thumb for the new local range? I assume it has to be relatively narrow since we want to stay in the vicinity of this global minimum identified by Sobol analysis.
If possible, could you please describe the procedure for this setup so that it continues Tsearch from the best Sobol design variant?
Thank you for your support!
