It's included in Ansys Fluent tutorial guide pdf , you can download it free.

We recently published a pretty powerful phase change model in COMSOL Multiphysics, a similar software, if you're interested. Feel free to contact me if you'd like to discuss anything.

Dear Karthikkumar Ramiyakrishnan,

I have attached herewith the Article & Video for your reference, which deals with fluent file for the simulation of melting/solidification of Phase change material Kindly go through the same.

ANSYS Fluent Tutorial: Analysis of Melting and Solidification of Phase Change Material (PCM)

I hope I have answered your question.

With Best Wishes,

Hi,

Kindly attached a zipped folder containing a similar project I've done on the melting and solidification of a PCM with Nano-Graphene particles.

You can view the geometry, material properties and settings I used for the simulation.

I hope it helps!
