Hi Ashish, thank you for your responce.
I don't think it's a model corruption problem. After Workbench closes I can open the project in a new WB and everything seems fine. I can add systems and analyze the systems with no errors or other noticeable problems. Is there a way to attach files to these threads? Or is there somewhere I can share the diagnostic file?
