hi,

I am adopting a new turbulence model in FLUENT using UDF.

For this I need to deactivate the k-omega models of the Fluent Source code and I need to define a new transport equations for the k and omega equations.

If any of you have an idea about how to deactivate the k-omega equations of the fluent, please let me know.

Regards Avinash

HI, I am not sure whether this option would help you. You can model the fluid zone as porus media. Assign zero resistence for porus media and you can apply Laminar Zone option.

I hope you can solve the transport equations using the UDS faciltiy and then provide the turbulent viscosity using a udf.

Hello Avinash,

Here you can see an example of a new turbulence model implemented via UDF. I hope it helps.
