Hello,

I am modeling thermal stratification in a tank full of water. Usually, the initial temperature which I use is uniform and equal to 25°C. Now, I want to model a special initial state. The temperature of the upper part of the tank is 62°C and the temperature of the lower part of the tank is 25°C.
It is the same fluid in the tank (the fluid is water). There is no wall between the upper and the lower parts.

Can you help me please for modeling this case?

I have attached a picture for the initial state which I want to model in FLUENT.

thank you in advance for your help
