            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,
