Thanks for sharing the Coanda Effect.
Btw, the real model is a free air injection (no paralel walls up or down after the nozzle, there will be a wall after the outlet region. Thats why i want to measure the distance). The first mesh had 29k cels.
The second one, 109k: Result: air injection similar to first simulation, but the 1st geometry has a greater flow for me now (physic - jet formation)
However, for the 2nd and 3rd geometries, the flow is still going down as if we had different pressures, but we dont have it (symmetric).
Could the mesh at the triangular zone be bad?
