Hi,

I have a question regarding the webinar of yesterday. If I am not wrong, it has been told that the k-omega sst model implemented in simscale requires a y+< 200. This sounds quite strange to me.

Indeed k-omega sst is a model obtained by blending two models, the k-omega and the k-epsilon (with more influence of the k-omega on the wall and the k-epsilon far from it).

I am not an expert of turbulence modelling implementation but theoretically speaking, if you have a too large y+ (like 200), the software will directly solve the k-epsilon equations, therefore switching your k-omega sst to a k-epsilon model.

I am maybe making some mistakes, but if possible it would be nice for me to get this clarification.

Thanks!

Fabio
