TAGGED: Algebraic, anisotropic, turbulent-heat-flux
May 31, 2022 at 4:32 pmdonmohsenSubscriberHello the community I have found that for implementing user defined anisotropic turbulent heat flux closure you can do it by editing ccl file like below:
DOMAIN: Domain 1
HEAT TRANSFER MODEL:
Option = Thermal Energy
TURBULENT FLUX CLOSURE:
Option = User Defined
uh = 1. [m^3 s^-3]
vh = 2. [m^3 s^-3]
wh = 3. [m^3 s^-3]
But when i run this ccl, it says there is no 'user defined' option available.
Can somebody help me please??
By the Way I wanted to Implement algebraic turbulent heat flux equation in CFX. I would be happy for any help.

What is the turbulence model that you are using? Are you using SSG Reynolds Stress model?
Anisotropic diffusion is not available for all turbulence models.

The CCL that you're referring to was a beta feature in CFX-5.7 (2004). A lot has changed in the software since then and this beta feature is no longer available.
