how to create a domain of density stratified water in ansys fluent using open channel method

Moving the thread into the Fluid Dynamics? Can you elaborate more on your concern?

I want to simulate movement of an object under water (sea), using multi-phase VOF method and open channel initialization. so i want to incorporate density stratification like in the actual sea

Yes you can do that with VOF and Open-Channel Flow but I do not understand the density stratification: Do you mean the density stratification Air/Water or the Density change of water due to temperature/pressure/salinity/depth..?
September 3, 2018 at 3:57 pmKarthik K RSubscriberThe 2nd one,Density change due temperature.. and how can i implement the the temperature difference in open channel..

If you define the density of water as temperature dependent then you will obtain a density stratification for the water. How to setup an open channel case can be checkedin Raef''s Tutorial : https://youtu.be/GU_4HNHVsDY
September 14, 2018 at 2:49 amKarthik K RSubscriberI know that density can be defined as a function of temperature. But how can i introduce that temperature difference to the water channel in my simulation

You mean you want to change the temperature with depth? You'll also need to set the inlet, and there are a few threads on here explaining the DEFINE_PROFILE UDF macro.
