Hi,
i'm running a large parametric sweep which turned out to dramatically slow down during the last few combinations. My machine has been crunching for days now and i'm wondering if there's a way to interrupt the sweep without loosing the results already generated...
anybody tried that before?

thanks, martin

This is an important question. I also would like to know the answer...

Hi,

luckily - you are here absolutely safe with COMSOL. Just make sure to press the "Stop" button in the progress window. This wil interrupt the solver sequence but keep all results that have been created so far.

More specifically, if you see more than one "Stop" buttons in your progress window, start with the one at the bottom, which marks innermost loop in a complex solver sequence. Then gradually move upwards with the stop buttons. If you'd stop only the TOP solver process, it would be terminated only when it comes to the next loop, so all the subprocesses would still finish their work beforehand and it might take longer to see the computation being interrupted.

Hope that helps - if not, let me know.

Hi, Sven!

Thanks for the reply!

How about running on a cluster without a GUI? Is there a safe way to stop the job?

Best!
