Hi, guys.
I want implement some turbuence models in my code.
I have noticed that some code limit mu_t/mu to get a robust code. Another choice is limit mu_t directly. In CFL3D manual, the author recommended the limit for mu_t is 10000.
Which choice is more proper and what is suitable limit value for each choice, How do you think?
Thanks in advance.
