Quickly open the "Problem Controller"
New feature!
When looking at convergence plots, you often find one of the controllers has an input that should be changed. For example, Controller_2 seems to be over-damped:
I don’t know when this feature was added (maybe it is undocumented?), but if you right-click on the controller, you see something new: “Edit Properties”
This takes you immediately to the controller you think needs fixing… and look what we find: Controller_2’s FDAMP is much too high.
Previously, you would need to search your model for the controller before opening. This new feature makes it possible to open it directly.
Comments requested
Do you need help understanding the “main” convergence plot and the controller plots? Leave me a comment and I’ll write a post (or more) about that topic.
Mike, I give some overview information in this post: https://davidkolman.substack.com/p/zero-is-a-terrible-starting-guess
Liz, two thoughts. (1) are all the controllers converged? I think it might be possible for the model to stop iterating, thinking it's converged, even though a controller hasn't hit its target. Take a look at the controller plots first, then check TOL and FSTOP specifications if something doesn't look right. (2) Look for instances of "kssignalnotcoverged" in KS EbsScripts (in Comp 93s or macros in "Expert" mode with KS). That function forces iterations to continue. Use the method in this post to find them: https://davidkolman.substack.com/p/automate-ebsscript-edits-in-a-suite
