      how to model a viscoelastic fluid in Asnys fluent that responds to the Phan-Thien -Tanner viscocity model

      I'm not familiar with the model, please add a screen shot of the maths.  You can write a UDF to model this: have a look as there are some examples on here and it's (sort of) covered in the documentation.

      You'll need to code up the model: simply the maths to viscosity = function (strain rate) and have a look on here for examples.
