Deformed geometry and prescribed velocity

Please login with a confirmed email address before reporting spam

Goodmorning to everyone,

I'm new, and I'm facing a problem with deformed geometry.

I want to deform a liquid domain under a defined velocity V that acts normal to the upper boundary of the domain, and under action of fluid velocity, u and v.

I use single phase flow and deformed geometry on 2D axisymmetric component. Velocity of liquid, with components u and v are referred to material frame (r,phi,z). I apply to the upper boundary a "prescribed normal velocity" with my velocity V, so it acts normal in the deformed reference (Rg,PHIg,Zg). How can i add as prescribed velocity u and v to deform my geometry, that are referred to material frame?

Thanks for any help.

Mattia
