The problem with k-omega continuity

toraman · December 21, 2014, 07:08

I m using k-omega sst model for 30 000 Re in a rectangular finned duct . But by the number of fins incresing, continuity is not obtained. Computed first layer thc. y+ value about 0,05 mm. and mesh elements ovre 500 000. I reduced under rel. factors especially moment.,Pressure or Spec.Diss.Rate but results never changed.
How can I do that could you give me some advice please.

Thank a lot.

For the time being, study is converged by reducing Spe.Diss.Rate.

Thanks anyway..
