Numodel-bundle – Numerical physics models with Forrester diagrams and auto-sized plots

A LuaLaTeX bundle for writing and rendering numerical models (Euler-integrated dynamical systems) directly inside LaTeX documents, aimed at physics teaching material. The bundle contains numodel (the modelling engine with stock-and-flow diagrams), numodel-plot (a PGFPlots styling layer that auto-sizes plots to whole-number tick intervals), and numodel-coach (exports a model as a CMA Coach 7 modelling activity).
