How to model elastoviscoplastic (EVP) fluids in ANSYS?

I’m working with ANSYS Fluent R20 + Polyflow and want to start research on elastoviscoplastic (EVP) fluids.

I’m looking for a way to model:

- Viscoelastic fluids

- Viscoplastic/yield-stress fluids

- Elastoviscoplastic fluids (elasticity + viscosity + yield stress)

I know Polyflow has built-in models such as Bingham/Herschel–Bulkley and Oldroyd-B/Giesekus/PTT, but I’m not sure whether it can model a genuine EVP model such as Saramito directly through the GUI.

I’d prefer to avoid developing a large UDF/C program if possible.

Questions:

1. Can Polyflow model EVP fluids directly through the GUI?

2. If not, is Fluent + UDS/UDF the best ANSYS approach?

3. Would COMSOL be easier for implementing an EVP constitutive equation without C programming?

4. What EVP model and benchmark would you recommend for a research project, and how should I validate velocity, pressure drop, stresses and yielded/unyielded regions?

*Looking for advice from anyone who has actually worked with EVP/viscoelastic/viscoplastic CFD*******
