I finished university 4 years ago but just now I am going down the rabbit hole of bond graph modeling and studying directly from the MIT class notes of Henry M. Paynter [1] while simultaneously using Simscape at work for modeling vehicle systems. I understand that bond graphs are the underlying mechanism upon which Modelica and Simscape are built upon(?).

Can any expert in this field give me some pointers. My current belief is that understanding the theory of bond graphs will give me intuitive understanding of just about every system I work with in my field.

I find that this field is surprisingly niche, as most of my peers have never paid special attention to it, but when I found about it, it seemed to me like a magic bullet for all my problems.
