Unable to incorporate buoyancy force in fluent- vof multiphase
 

Hello, I'm trying to simulate the bubble formation from a submerged capillary and the bubble forms but just sticks to the capillary instead of rising up in the liquid.

Below are the model specifics:

Interface tracking: VOF
Interface construction: Geo reconstruction
Pressure coupling: PISO and PRESTO
Time : Implicit
global courant number: 0.5;
time step variable starting with 1e-9 seconds
Inlet velocity: 2.49 m/s
orifice diameter: 0.32 mm
