hello i am a beginner of openfoam !

as i run the example related bubble injection, i can know there is an option related to bubble injection called "fvOption" in openfoam.
(for example adjusting the bubble injection start time, bubble duration time , the location of bubble injected to water (point, cellzone etc..))

related this, i have some questions..

first, i want to inject the liquid water instead of bubble. but when i used fvOption to simulate the water injection, an error has occured..
can i use the fvoption to water (liquid)injection instead of bubble (gas) injection?

second, when i used fvOption to simulate the bubble (gas) injection, i set the location of bubble to point (for example, (0 0 0.5) etc.. ). however, i want to make the bubble comes out from the face or volume instead of points using fvOption.. is it possible? (additionally, i want to know the meaning of cellzone, cellset respectively and difference between cellzone and cellset in fvOption..)

thank you for reading this.
