An error with parallel optimization
Posted: 14 Feb 2021, 09:38
Hello,
I am trying to optimize (increase the area) on-momentum 4d dynamic aperture with just two variables and two covariables
After running on windows 10 with elegant 2020.5 Dec 11 2020
you may see in %s.opt file that there were some optimization steps and after another one an error was issued.
The error message is
What am I doing wrong?
The next question is that after this simple try I want to optimize dynamic aperture at several energy deviation points with about a hundred variables. How do I access the DaArea term at several energy points?
Anton
