Flow of Fluid within the Same Fluid

I want to know if what I am doing is correct?


I would like to simulate a stream of water coming into a Tank which is already "Filled" up with the same kind of Fluid. (in my case here is Water)


What I imagine flow simulation to be doing normally is that:-


The stream of water simulated, is coming into an Empty Tank.



What I believe which (I could be totally wrong here) is:-


The stream of water would act different should there already be Water pre-filled inside the Tank.


To emulate this, do i create a Fluid Subdomain of the same Fluid inside of a Computational Domain and simply run the analysis? Or is there an option whereby i can suggest that the Computational Domain is already filled with water??
