Hi! I need to model a two-phase flow with air and a viscoelastic glue. Are there any in-built viscoelastic models available for fluids (like UCMaxwell, Oldroyd-B, PTT, etc) ? I can find such models under solid mechanics tab (for solids) but are there any similar in-built viscoelastic models for fluids ?

Hi!

A visoelasticity cannot be applied to fluids, can it? A fluid never recovers elastically.

If you mean visoelastic solid parts inside the fluid, then those parts should probably be modeled as solids.
