Error in compute process - No Active Application
 

Hello and Good day to all,

For my computation, I am using a research license at school. I ran fluent with Parallel Run Settings and used "4" as the number of processors. I let my computation run over the weekend and I get the following messages (Please see below)

After reading a couple of threads, I am noticing that my problem might be with the license server. I also noticed that in Workbench, I see a message that says "License server lost for 5 min" "License server will time out if not reconnected".

Can anyone recommend how I can continue my computation? Would I need to contact the school administrator? I click calculation again, and the window shows a message "There is no active application".

Thank you very much.

I am currently having the same issues at my university

Were you able to fix the error?
If yes, then could you please share the resolution ?

MPI error
 

I am having issues with MPI too. It seems when the connection to the Internet is cut, the calculation using parallel computing ends as well. Here is the last message error in the task page:

MPI error
 

Does anyone here know of a workaround to this Fluent error with the local processor? I am using Intel by the way. I have been trying to understand this for more than a week already.

I've worked this out. When running Ansys Fluent parallel processing, the software should be able to detect a network connection for the MPI to be validated. Even if there is no active Internet connection as long as it is stable and not fluctuating, the run/simulation will continue. I've encountered the same many times already and this recourse has helped me run the calculation continuously.

Hi iancmlositano, Could you please give more detailed information to resolve this issue? Many thanks!

Problem solution: h flag
 

I had the same problem, but after a long simulation time.
In my case, I was able to solve it like this:
Write case and data.
New initialization (again), restarting all variables.
Run a few timesteps
Import old archived ".dat".
Saving new cas and dates
Run normally

Thanks, CelsoMurilo. Good idea. It is worthy to try in the future.
