Hello. I have created a parametric model of a simple truss structure and have applied loads to it for cross-section optimization using the Optimize Cross Section component. I have maximum utilization and maximum displacement as constraints. The problem is that when I set the maximum utilization to 0.8, I get an error as shown in the image, but when I set it to a smaller value of 0.7 or 0.6, I do not get an error. I am puzzled by this result, since the smaller the maximum utilization ratio, the more restrictive the conditions should be. I would be happy to know the cause.
Hello @Bikamuse46,
I’m currently working on enhancing the convergence of the cross-section optimization algorithm. The message you’re seeing is just a warning: the maximum displacement should be 10 cm, but after reaching the maximum number of iterations (default is 5, adjustable in the component’s submenu), the displacement is 10.03 cm—an insignificant deviation that can typically be ignored.
