ANUGA Reference

ANUGA is the open-source two-dimensional hydrodynamic engine that powers every Hydrata simulation. This section is reference material: it documents how the solver works, the format of the scenario package Hydrata produces when you build a Scenario, and the configuration and defaults applied to each Run.

If you want to build and run a model in your browser, start with the Getting Started tutorial instead.

In this section

  • Concepts: the triangular mesh, Manning's roughness, boundary conditions, and the simulation pipeline.
  • Package Format: the directory layout of a scenario package, the self-contained artifact produced by building a Scenario.
  • scenario.json Reference: every field in the simulation configuration file.
  • Defaults: the constants applied when a Scenario does not specify an explicit override.
  • Run ANUGA Yourself: install the run_anuga package and run a scenario package on your own machine.

Note

Hydrata runs the same ANUGA solver and the same pipeline. A scenario package downloaded from Hydrata produces directly comparable results when run locally with the same inputs, so your work is always portable and reproducible.
