I have been working on and just officially released [**BondGraphs.jl**](https://github.com/jedforrest/BondGraphs.jl), a Julia implementation of the bond graph framework. [Bond graphs](https://en.wikipedia.org/wiki/Bond_graph) are an energy-based modelling framework that describe energy flow through a physical system, and are especially useful for modelling multi-scale or multi-physical systems.

I’ve tried to make BondGraphs.jl integrate with the wider Julia modelling ecosystem, including ModelingToolkit.jl and Catalyst.jl. The package is still in its early stages and undergoing a lot of development, so feedback is greatly appreciated.
