Re: Overmixing in stripes

Hi, I don't think the vertical mixing of my model is working fine. If I check AKv with the limiter, just the layer befow the surface the value is too high almost everywhere in the model. The area where the stripes appear is where AKv at the limit persists for longer in the vertical. https://i.imgur....
