how to use the different turbulance model in one case?
I want to use the different turbulance in one case , before the transistion point,I want to use the laminar model ,after that use turbulace model.
once i saw someone do like this. Do i need use the UDF? Which macro should i use?
thank you for your attention! Need your help.
You can divide your domain to 2 separate part. These parts are separated at the transition point. In the viscous model panel, choose the appropriate turbulence model. Then in the boundary condition panel, where you have 2 fluid zones choose the one that you want to be treated as a laminar zone. In the related panel just check (activate) the "laminar zone" option.
Wish it can help you
