Fluent 18 steady propeller simulation with overset

      Hello,


      I am using Fluent 18.2 with the overset method to simulate a rotating propeller. I am interested in the unsteady solution, for which it is recommended to start with a steady simulation. However, the Frame Motion option, which I usually use for steady propeller simulations without overset, is not compatible with an overset mesh. So I'm wondering if there is another way to obtain a steady solution first? 


      Otherwise, I would have to start the simulation transient right away, which seems to work but probably takes a long time to finish. 


      Best regards,


      Soren

      Overset is compatible with steady-state solver and MRF with the current releases.


      If you cannot update just start with transient or start steady without MRF.

      I attached the message I get when I want to select the Frame Motion option in the Cell Zone Condition definition. Am I missing something?

      I wrote in the current releases.

      I see, thank you.


      I will see if I can update to ANSYS 19.
