Hi,
if it is a time dependent study, you can continue the study. You have to interrupt the study manually by using the STOP buttons. If it completes normally, the continue option is not available anymore. @Comsol: This should be changed ...
Other models may be continued by setting up a second study that takes the solution from the interrupted study as initial condition. This works for time dependent too. You have to set the start time of the second study equal to the stop time of the first.
If your model comprises a parametric sweep things may get complicated, no solution here in this case so far.
Cheers
Edgar

Thank you very much! Another question is that I would like to get the macro separation efficiency of water-in-oil emulsations. My thought is to get the size of coalescence droplets, but I donot need to focus on the the process of droplet-droplet coalescence. That is to say, donot need to calculate the interface behavior of droplets because the calculation takes too long time with Level set method. Could you please help to propose any other methods to get the efficiency? Thanks again.

Sorry, we don't do any CFD work. But maybe others can help.

Dear Edgar,
I know. I mean that do you have any module to do coalescence but not that slow as level set.
Kind Regards,

Dear Edgar,
I am using level set method. It seems that even though I set up a second study that takes the solution from the interrupted study as initial condition, the second study calculate from the original initial condition, and I got the same results as the first study. So, does your method fit in level set method? Thanks.
Kind Regards,
Bin Li

As I said, we don't do CFD so I can't tell anything about the level set method.
