Hi Scott,
Thank you for reaching out to us, I will help you figure out what goes wrong in the simulation.
The error you received could stem from a problem in the OpenSees simulation or in the damage and loss assessment. First, I suggest excluding the possibility of an OpenSees issue.
Please navigate to your working directory (C:/Users/KPP/Documents/PBE/LocalWorkDir), then go to the tmp.SimCenter folder and you should see a log.txt file there. If you shared that txt file here, it could help me a lot in understanding the issue better.
Thank you,
Adam
