Hi!

I hope you are all doing well. I am posting because I am tying to run an eigenmode simulation using a slurm script on a high performance computing cluster, but I am running into this error (the image is from the log file that is automatically created after submitting the slurm script):



I tried to delete the asol file and rerun, but the issue persists. The simulation I am trying to run is a test, so it is just a box with vacuum assigned as the material (pretty simple to run so I am not hitting any ram limits or any storage limits). When I tried to run this in interractive mode, it works fine, so I do not think there is something wrong with the file or with my permission to store the solutions on the working directory. 
If any of you had any ideas on what else to try, I would really appreciate it. Thank you in advance!


Here is my script:
