Hi All,

I'm trying to simulate flow of a highly shear thinningin Fluent. For this, I wrote a UDF to incorporate the Carreau-Yasuda model into Fluent.
However, for the second half of my masters thesis, I also need to evaluate the viscoelastic effects of the fluid. I would hate to go to Polyflow for this. (Partly coz I'm done with a major part of my thesis, and also coz I dont know Polyflow!)

Does anyone have a UDF for a viscoelastc fluid in Fluent? Maybe UCM model or PTT model? Any ideas will be appreciated. I have never written a complicated UDF before (I'm assuming this one is going to be complicated), so any help on this topic will be highly appreciated.

Can you share your procedure to model this shear thinning in FLUENT? I know that OpenFoam offers more option on shear thinning and viscoelastic modeling...
Thanks
