I want to model the channel flow ，but with time passing， it cant be turblence but laminar . Here is my steps in modeling：
1.Get the convergence of rans steady results
2.type init-instantaneous-vel to get an initial field of les
3.switch to les model and carry on simulating

but there will be a laminar flow.

if i can use a udf to initialize a filed without Rans results？，could anyone send me a udf about that？

thanks！

What's your inlet boundary condition? Check it. Is it a laminar inlet?

Inlet condition is periodical condition with mass flow rate

According to the mass flow rate，the Re_h=3000 Re_tua=138
