The Setup under Fluid Flow (Fluent) is not working and while meshing, it takes longer than usual.
Set-up is missing information by the looks of it. Can you right-click and edit Setup?
Thank you for your help. Btw, the problem was because the ansys file I opened was corrupted and the problem has been fixed.
