I am currently trying to build a model of a square fuel tank (will start from 2D if success will move to 3D), I am wondering what are the steps to build the model that can simulate a square fuel tank contains half jet fuel vapour and half jet fuel liquid in a freezing temperature (approximately -70 degree C). The result will be looking at the temperature profile over times. I am thinking about transient thermal in the workbench but not sure what are the general procedure.
Thank you very much!

"contains half jet fuel vapour and half jet fuel liquid"
Can you please elaborate on this, perhaps by sharing some illustrations?
I would recommend you to try this out in the Ansys Fluent.

In order to carry out the simulation, I advise using the multiphase model (VOF).
For more details about the multiphase, please refer to the theory guide: Chapter 14: Multiphase Flows (ansys.com)
Also, please refer to the user's guide: Chapter 22: Modeling Multiphase Flows (ansys.com)
Hope you find this useful

Sorry if I didn't make the question clear enough, I am going to build a simple square model with fuel already inside. I want to place the model in a very cool condition (about -70 degree celcius) for a certain time, and I want to see the temperature contour plot and observe that how long does it take for the fuel inside the square tank to reach a certain temperature.
Thank you very much!

OK, so the multiphase part of the examples is OK, you need to patch the fuel level. Note, you'll need a vent otherwise the whole system is going to get interesting unless the gas is compressible! Don't forget you'll need density to vary with temperature & turn gravity on if you want to see natural convection.
