Gravity value : g(z)

Hi, Do I need to put a gravity value: g(z) in my simulation?
Here is my project link: https://www.simscale.com/workbench/?pid=4930889061328870686&mi=spec%3A3d16b6a1-501b-40fc-b8dd-9a75219d9041%2Cservice%3ASIMULATION%2Cstrategy%3A22&ps=analysis%2Fmodel

Can anyone tell me the answer?
Thank you.

Hi there,
Thank you for posting on the forum! As I see, you have a convective heat transfer. During convection, gravity plays a role to set convection currents in motion. Hence, you need to setup Gravity.
Hope this is helpful :slight_smile:
Happy Simulating!
