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

This bundle provides Lua tools for writing and rendering numerical models, specifically Euler-integrated dynamical systems, directly within documents. It is intended primarily for physics teaching materials.

The bundle consists of:

  • numodel, a modelling engine that supports stock-and-flow diagrams; and
  • numodelnumodel-plot, a PGFPlots styling layer that automatically sizes plots so that axis ticks fall on whole-number intervals.
