user-defined turbulence model
Can anyone help me how to implement user-defined turbulence mode.
For example I dont have V2F model in my Fluent. So could anyone help me how to implement V2F model in Fluent using user-defined. I was trying last one month...Many thanks in advance.. |
hello,
you can use the v2f model through TUI :) Best regards |
Sir, Thank you very much for your reply.
I have seen the commands define/models/viscous/user-defined/ after this, Could you explain how to give the damping functions etc... |
are you talking about the near wall treatment?
|
No. there are plenty of low-re-turbulence models available. Howver In fluent only 6 low-re-turbulence model is available. If I want to use user-defined low-re-turbulence model. Then how to use that model in Fluent.

in my version of Fluent (v.13) the v2f model already exists (with the command define/models/viscous/user-defined/v2f? yes)
If you have a previous version I don't know how set-up it by UDF...:( |
Thank you very much for your reply.
I am using same version Ansys-Fluent 13, when i enter the below lines are coming.. /define/models/viscous> user-defined Viscous user-defined functions: ("none") Enter turbulent viscosity function ["none"] Enter TKE Prandtl number function ["none"] Enter TDR Prandtl number function ["none"] Enter Energy Prandtl number function ["none"] Enter Wall Prandtl number function ["none"] |
sorry, I made a mistake
the command is define/models/viscous/v2f? :) |
Ok. I dont have this option in viscous. In help it was mentioned that
user-defined-transition/v2f can be enable. But I dont have user-defined-transition |
