Relative Velocity Formulation option is unavailable?

      Hi all,

      I am a rather fresh user so it will be awesome if anyone can give me an insight about the issue.

      Readinfg the Ansys Theory Guide, I learnt that the Relative Velocity Formulation option is more suitable in flows dominated by rotations so I have decided to use it in my project. However, it is greyed out, unavailable under the "General" Settings. I am using Pressure-based solver Coupled scheme, which I read some posts saying its not compatible? 

      I am not sure why the option is unavailable. So wondering if anyone can give me an insight and suggestion. Thanks!

      Option only available for Pressure Based Solver.

      Hi Amine, I do am using pressure based solver, but it is still unavailable though.
