suppress the body??
 

Just consider I am modelling a flow in which water comes from a inlet on top an it splashes on the bottom wall of tank kept 40 mm down the inlet and then distributes in 6 symmetric outlets in the plate.
I am using a VOF model with primary phase as air and secondary phase as water.

Just tell me one thing that during I make the geometry should I suppress the tank (body in which I filled my fluid domain) or continue with it.
Will it make some difference.

You should suppress it.

then in boundary condition should i set faces of solid generated as walls or something else..
There is no need of interface .. Is it???

And one more thing initially my tank is empty and water in coming from inlet so what should i do during initialization and patching/adapt.
please explain a little
