I need to simulate this in fluent.

Take a bubble of radius 1 mm with internal pressure as 3 kPa, while the outside liquid is at 1 bar pressure. This bubble is at a distance of 1.1 mm from a flat surface. Gravity acts vertically down.

the bubble is of vapour.

I used multiphase model with VOF.

I created a Rectangular domain to simulate it in 2D with suitable dim...
