problem with UDF for (v2-f) turbulence model in fluent
 

Hi.
I found the v2-f UDF (Durbin turbulence model) to link with fleunt software, but it contains several errors when I compile it. I also use interpret option for udf in fleunt but it is not working.what is the problem? please help me.
(I found two papers that the writers claimed that they could do this work without any problem.)

Cheak with header file, and the udf use

You post the udf and corresponding papers here, and we can help you check it out.

thabk you.here is the udf.

any reply? I am waiting for anyone using this turbulence model.also this model released via the original package of FLUENT. could anyone check it?

Sorry,but I can't help on the UDF file.

If you use Fluent 6.3.26,you can activate v2f model by typing

(allow-v2f-model)

in the console window.

Hi artemiss1984,

I would like to use this udf but I do not understand in which equation they use the UDS_FLUX and how program recognize the difference between UDS_FLUX cases and diffusivity cases as they have same name?
I am trying to solve simple pipe flow but I am getting access violation errors.
can you help me in order to solve this problem!
thanks in advance!
