v2f model implementation for airfoil in FLUENT
 
Hi, I am trying to simulate airfoil flow using v2f model. I came across the udf from a website to implement the model:

http://www.fh-pinkafeld.ac.at/fhplus/download.htm

I think I have the case file setting correct. I ran a simple channel flow and everything works fine. Whereas for the airfoil, the values go to Nan after about 50 iteration. I have tried reducing the urf and gone till 0.1, but the solution does blow up. The cd and cl values are very very high. To keep things simple its just a 2d steady state simulation.

If anybody has experience with the implementation of v2f in FLUENT, I'd appreciate if you could share your experience.

Thanks

hi, instead of using UDF u can get the v2f model in Fluent turbulence panel itself. following is the procedure: define>model>vis>turbulence> after this type: <v2f model> enter

hi Sunil,

Can you help me about editing the source terms v2 and f in fluent?
did you edit them in the TKE or?
thanks in advance!

hello, I try to reach this website, but it did not work. why?

Does anyone here has the UDF source files in the address mentioned in the very first post of this thread?
The files seems to have been removed from that address.

Thanks,
Ali
