I want to solve below error. can any one help me solve this?
Without any more information I'd guess that you upgraded to AECOsim SS6 but that (part of) the dataset was copied from the SS5 dataset. Have you tried utilities/key-in and "dg update"? Please provide a bit more information like exact version numbers of the software you're using and a bit more background as to how you arrived in this situation. Thank you!
