In the browser#
Nothing to install: the GUI and a JupyterLite notebook run the NumPy solver in the browser (Pyodide).
The GUI: compose and run a case, share it via URL (Using the GUI).
JupyterLite notebook: the whole stack,
Model→SystemModel→NumericalSystemModel→ C++ codegen → NumPy solve.SWE game: a shallow-water game that runs in the page.
Other backends (JAX, AMReX, OpenFOAM) run on your machine: Install or Containers, then connect them to the GUI.
