Hi,
I'm trying to simulate a Hydrofoil (2D) near the free surface with fluent but it doesn't converge. I'm trying to reproduce the set up I've found on this paper: https://doi.org/10.1016/j.ijnaoe.2020.11.002.

the set-up:
k-w SST and VOF
Pressure velocity coupling: Simplec

BC:
Pressure Inlet,
Pressure Outlet,
bottom: no slip
hydrofoil: no slip
top: symmetry

Th residuals of the continuity always stays around 1 and never converge. I dont understant what I'm missing.

(First time, I'm posting here so if you need more information don't hesitate)
