hello,

how can I pause simulations and restart them later. I don't want to use the stop button, because then I have to start from the beginning.
Is that feature even available? Couldn't find anything.

I'm using Comsol 4.2

Thanks for your help

Depending on your operating system, you may be able to pause the program (less than ideally), but I need this as i run COMSOL on my laptop which uses the network research license at my school, if I leave and just let the computer keep running without the network connection, it eventually quits completely. There is a method in OSX using the kill -STOP #PID that can pause the program. i have tried it, shortly, and will be trying it this afternoon on my ride home for longer term. It goes like this:

-open 'Activity Monitor' , or use ps -axww | grep COMSOL and find the COMSOL instance with a lot of CPU time
-type 'kill -STOP #PID'
-where #PID is the Process ID listed in activity monitor or the first number listed on grep (they should match)
-the program should now instantly be stalled but still open, and probably unresponsive
- type "kill -CONT #PID' to start it up again

Hope this helps, or at least guides you a little. This would be an extremely useful feature (almost like pausing a virtual machine). Good luck.
