About TSNet-TS

TSNet-TS is an online water hammer and hydraulic transient simulator. It runs the Method of Characteristics on water distribution networks described by EPANET .inp files, entirely in the browser — no server-side hydraulic engine for the demo.

The project is a TypeScript port of TSNet by Xing and Sela. The original Python package is described in:

Library and web app

• @tsnet-ts/ts-net — MIT-licensed TypeScript engine (npm)
• github.com/tsnet-ts/TSNet-ts — source for the library and this demo
• This website — free noncommercial online transient simulation (PolyForm Noncommercial)

What you can simulate

Valve closure and opening, pump shutdown and startup, pipe burst, background leak, demand pulse, and surge tanks. Friction can be steady, quasi-steady, or unsteady. Steady-state start-up uses EPANET demand-driven (DD) or pressure-dependent demand (PDD).
