Default How to couple transient thermal solver with fluent solver?

I am doing a thesis project on laser parameters optimization (speed, intensity) in laser surface hardening. For simulating laser, I did a 3D simulation of a moving gaussian heat source on the eutectoid steel surface using [URL=""][this] plugin. It works in workbench mechanical. Using this plugin I got the temperature profile in a 15*20*8 (mm) domain.

Now I want to do a 3D simulation of pearlite to austenite transformation in the heating cycle (and cooling too, if possible) as laser moves on the surface. Pearlite is considered a layered structure, interlamellar spacing 0.1um to 3um, composed of cementite(6.67%C) and ferrite(0.02%C). Right now I am considering only carbon diffusion with Fick's law to determine the concentration profile. But, I am open for other approaches too.

I am new with Ansys and I heard fluent have some models for my problem so I want to couple transient thermal solver with fluent. Also, please tell me if fluent can solve my problem.
