Getting started

The Model Builder is a browser-native drag-and-connect canvas: drop nodes, draw pipes between them, set boundary conditions, choose a fluid, and press Run.

A minimal working network is: one pressure boundary (a reservoir), a pipe, and a draw (a junction demand or an atmospheric open pipe). Add pumps, valves, and fittings from the palette; set the system fluid in the Fluid Editor; then Run.

Load one of the built-in examples to see a complete, solving network you can pull apart.

• First time in the builder; sanity-checking a new network shape.
