Is there any laminar-turbulence transition model in COMSOL?

Hello, I have turbulence transition in a model. Should I use turbulence model (ex. k-omega)? Or, is there any transition model in COMSOL? (ex. gamma-theta)

How do you believe that COMSOL k-omega interface can accurately simulate laminar zone? or transition zone?

Dear Mr Lee,

There is a local, correlation-based transition model (gamma model) in the Turbulent Flow, SST interface. It can be activated in the Turbulence section at the physics interface level.

Best regards, Mats Nigam
