Hello,

I inadvertently opened model from 2021R2 to 2023R2 and now my model refuses to solve and ends in a fatal error:

Random write error, I/0 status error = 28

I have more than enough disk space to solve the model so I know it isn’t a drive  issue.

Additional background info
I am running prestressed modal analysis. I have all the restart files included R00#, ldhi, rdb files to initiate the perturbation run. It solved perfectly fine in the Ansys 2021 version

Have others here encountered similar issues, and if so, how was it resolved?

Thanks,
Nelson

May we assume that you chose Exit > NoSave once you realized the newer version didn't work?  If so, why don't you just revert to the previous version?
