Temperature field without energy option

Shoh · July 15, 2020, 19:46

Hello.

I want to obtain the temperature field without 'Energy' option in the 'models'., i.e. with 'Energy (off)'. For this, I tried to use a user-defined scalar equation, but I'm not sure how to use it. I would really appreciate it if you let me know.

Also, if we are solve the RANS equations for the flow field, we may solve the mean scalar equation for the passive scalar (temperature) together with the gradient-diffusion hypothesis. Then, how can I set the turbulent diffusivity ratio (in this case, turbulent Prandtl number(=alpha_t/nu_t))??

If possible, I would also appreciate providing uds script.

Thank you.
