Default K-E values not converging

Hi Guys,

I am running a simulation using the standard K-E model.

The problem is that whilst monitoring residuals I have noticed that all the variables e.g. x, y ,z velocity etc are converging but the kappa and epsilon values are extremely unstable and diverging.

Can anyone help with this please? Thanks.

Check you grid resolution before altering the model coefficients.
