Hej,
my FSI doesnt stop if i click the stop button in solver control, even after finishing a stagger and coupling step. Anyone else faces this problem?
Is there any way to stop a FSI calculation by terminal commands like cfx5stop for fluid calculations?
Regards

Sorry I don't have an answer to the FSI issue; but I was wondering, where can I enter cfx5stop in the solver window or change run window to stop it when the stop button doesn't work?

you can stop calculations via terminal commands in cfx with:
[dir of cfx5stop]/cfx5stop -dir /path of the calculation folder
thats for linux, if u use windows i dont know if it works the same way, properbly via cmd u can use it as well.

Are you using workbench? I've noticed this problem too since installing v14.0. I just use the stop in the project page now and click "interrupt solution" that always works. But don't hit stop in the solver manager than immediately hit stop in the project page too. that screws everything up!

Hej evcelica,

yes i always pressed the stop button in the solver management (AnsWB14) and it sometimes just never stoped. I ll try it with interupt, didnt know it stops the solution with a res file as well.

Yeah, I've seen it happen too.

peterputter solution of using cfx5stop should work. In fact, what both the cfx5stop and the stop button do is create a file called 'stp' in your simulation temporary folder (the one with a '.dir' appended). So you can just go and create that file manually in any OS. I've never used cfx5stop because manually creating the file is just a lot faster.

In linux, you can use 'touch stp' inside the .dir folder. In Windows, just right-click to create a new file called stp. Your simulation will stop cleanly, that is, with both a res an a rst file.

If you're running inside Workbench, to find out where the .dir folder is you can look where the WB temp folder is set to. Or, if you've previously saved your project, it should be inside a something like '<project_name>_pending/dp0/CFX/'.

Hope that helps.

Cheers

Just to add something, creating a file called 'trn' has the same effect of pressing the backup button: it creates a backup (.bak) file, which is pretty much a res file with a different extension.
