Dear Seluk,

I'm afraid that it won't work, because the UDF of viscosity will surpress only the turbulent viscosity from the k-e and not the cmu cte. You can calculate inside your UDF and use it to estipulate your viscosity, but I'm quite sure that it won't change the constant inserted from the user.

Best regards

Dear Lourival,

it is an old post but I am hoping I will get positive response.
So, how should change CMU?
