Applying spring force onto solid PCM while melting

I am simulating a scenario involving a 2D PCM rectangular domain where the bottom side is heated. The bottom wall contains pores to allow liquid PCM to seep out. Additionally, a spring is attached from the top, with parameters: spring constant and natural length (which equals the height of the rectangular domain). Initially, at , the spring is fully compressed to a length , exerting a force onto the solid PCM. As time progresses to , the solid PCM displaces by , altering the force to . This force diminishes to zero as the entire PCM melts and the spring returns to its natural length.
I am familiar with simulating PCM melting using ANSYS Fluent. However, I am seeking guidance on how to incorporate this spring force into the model using Fluent alone. Someone suggested that this might require addressing it as a Fluid-Structure Interaction (FSI) problem involving Fluent + Structural. Nevertheless, I believe there should be a method to accomplish this within Fluent itself. My primary challenge lies in how to integrate this varying force and how to define it as a function of the solid PCM displacement. The attached figure provides visual clarity on the setup. I appreciate any advice or insights on implementing this spring force into my Fluent simulation effectively. Thank you!
