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.. |

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... |

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... |

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 |
