License loss after solving

[compositeFEA]

Hello Ansys users,

My question is about the way that Ansys deals with the license during solving and post-processing. I am using the Academic Research license in Batch mode and we only have 5 licenses of that type in my department. When a license is available, I launch a job with the Product Launcher and I presume that this license is now reserved for my job until it is done. But sometimes (not everytime), at any moment during the job process, I get an error message telling me that there is no more license available, then the job is aborted. Is this possible that Ansys takes a license for the solving process and then releases it for the post-processing, allowing other people to use it? If so, that is a problem for me since my APDL script tells Ansys to go back and forth between the /SOLU and the /POST1 processors... I know that Ansys can sell specific licenses for pre/post processing and solving, but to my knowledge this is not what we have. Any information would be appreciated!

No, the ANSYS Academic Research license is an integrated or single-task license, which means that if you use it for a batch run, it is used throughout the analysis run.

If this is an intermittent problem, perhaps it could be due to network instability? The ANSYS client checks in with the license server periodically. If it cannot do so for a certain period of time, it will exit.
