Issues with resuming time-domain simulation due to incomplete data export

Please login with a confirmed email address before reporting spam

Hello

I am currently running a time-domain simulation on a large model, which requires significant disk space to store the entire solution. To manage storage efficiently, I am using the "Store in output" feature to export only the relevant parts of the geometry. However, the simulation's runtime exceeds the job time limits on our cluster, which prevents me from resuming the calculations using the -recover -continue options in batch mode. This is due to the lack of saved data in regions that were not included in the output, which causes issues with providing consistent initial conditions for restart.

I would appreciate any suggestions or solutions to resolve this issue.

Edit: One possible idea that I'm not sure how to implement, is to find a way to store the full solution for the last time step only withing the recovery file. Once a new time step is computed, the previous recovery full solution is replaced by the new one.
