Adjacent cell zone
 

Hi, I have a question about cell zones. I have 2 boxes, one inside the other. The inner box has water and this box is surrounded by air (the region between the two boxes). How do I ensure that the "adjacent cell zone" to the inner box if defined as water, is indeed inside the inner box?

Any advice is greatly appreciated, thanks!

select and open setting of the boundary condition of the face. It have been written in that menu box that which zone is it's adjacent zone.

Hi Saeed,

Thank you, yes I knew that about the setting but my question is, which side of the box is the cell zone adjacent to. When the box is surrounded on both sides by two different fluids, how do I know which side "adjacent" refers to? Is it always the inner part of the box?

Thank you so much for your help!
