Remove Air Bubbles

– This checkbox (which is checked by default), helps to avoid any space between the fluid and an obstacle.
– The result depends from the mesh of the obstacle and from the domain resolution.

– As you can see in this example, not all ‘air bubbles’ are removed, producing a little weird simulation also when this option os checked (actually I used an opaque material for the fluid Domain to help to understand what this parameter does and a low domain resolution but as usual my goal is not to render realistic simulations!).
