Restart a acusolve calculation on supercomputer

I use AcuSolve solver on a university's supercomputer.

When using supercomputer, we need to specify the usage time (continuous calculation time) on a job script. According to the terms of use, the usage time that can be specified is up to 24 hours, so after 24 hours the analysis is terminated even if the calculation is incomplete.
It seems that it is possible to set "Restart" conditions in HyperWorks CFD, but is it possible to restart an analysis that was terminated on the supercomputer, by submitting the job script again?
Could you please tell me how to do this?

    When you run the initial job, you'll want to specify how frequently to write Restart Output.  (That should be in one of the sections under the Solution ribbon > Field section of Outputs.  This will modify the RESTART_OUTPUT command in the input file.  Then you can restart from the last available restart output set.  (If no Restart output was written from the previous run, there is no possibility to restart.)

    If there are no changes to be made to the run - only continue from previous - and restart output is available, you should be able to issue the same acuRun command as before, but with adding this option
