Composite Size optimization stops after iteration 0 without any error
Hey,
so I've been working on a composite optimization of a formula student monocoque and run into a problem.
Following the tutorial preparated everything for the continuous size optimization and started the optimization in optstruct, but after iteration 0 and iteration progress 93% i just stops without an error and says 'job complete'.
why is that? I've tried everything i know so far. I inpected the .out file and after the design property table of iteration 0 there is nothing more, the file ends there.
On other design steps of the same model, I got it all the way though from freesize to shuffle with no problem. just this latest step is giving me trouble. I even can run the various optimization steps again with no problems.
Any sugestions on why this isn't working would be great, I sadly can't share any (.hm or similar) files due to non-disclosure.
Thanks
Pascal

HI,
Unfortunately, I don't see any data after 0th iteration from the .out file.
Please share .out file for Shuffling to see which constraints are violating.

Hi,
That's exactly the problem. The optimization just ends there for no reason. So I don't have any other files from further optimization steps (discrete size or shuffling).

HI,
Can you try on another machine if you have access?

Hi,
Already did that with no success.
What I really don't get is why the freesize does work and the continuous optimization doesn't.

Hi,
I am able to run on my machine without any issues. I can see that optimization progressed beyond 1st iteration.
Can you update to 2017.2.2 (latest solver patch) and check if that helps?

Hi,
that's weird because i have the latest version. I'm gonna try reinstalling the whole suite again and deleting all config files.
Hopefully this will help.

Hi,
From the out file, you shared I see you have 2017.2.1
2017.2.2 is the latest.
