      Hello,


                  I have to know what kind of viscous model and other properties for getting appropriate values of lift and drag coefficient. Iam using 2d model. I am getting fluctuation of values each time when I use k-omega and k-epsilon models.

      Hello Ananth,


      Thank you for creating a new post for your question. This might give you more visibility since your previous post was already marked 'answered'.


      As I mentioned in my previous post:



      • Would you elaborate a little on your mesh (especially the boundary layer mesh)? And which wall models did you use for k-eps and k-omega? Could you also elaborate a meshing strategy?

      • Can you please check the reference values for both the solutions and ensure they are the same?

      • Have you performed mesh independence studies?


      Thank you.


      Best Regards,


      Karthik
