Showcase · See it solve

Engineering analysis that usually needs 3–4 desktop seats — in your browser.

Water-hammer transients, multi-fluid process utilities, and NFPA-13 fire hydraulics — solved by the same browser-native engine. Every figure on these pages is from a real solve you can reproduce in the builder. No install. No per-seat licence.

  • Transient water hammer with a CAESAR II force-file handoff
  • Steam, gas, two-phase and slurry — one tool, one login
  • NFPA-13 fire hydraulics with §28.4 supply-vs-demand
  • A project console: register, Gantt and earned value wired to the PHA
  • Every result is a real production solve, not a canned demo

Four flagship showcases

Each one is a working example, reproducible in the builder

Open any showcase below to read the story and the verified numbers, then click straight through to the live model in the builder. The figures on every page come from a real production solve — we tell you exactly what each run proves, and where the honest limits are.

Transient · Water Hammer

Surge & Slam

A rapid valve closure on a 4 km rising main slams it to ~32 bar and into deep vacuum — real water hammer. An air chamber stops the column separation at the pump manifold, and a power-failure pump-trip hands the pipe-stress engineer a 368 kN CAESAR II force file.

Multi-Fluid · Process Utilities

One Tool, Every Fluid

Condensing steam, natural gas, two-phase air-water, and settling slurry — the same browser tool covers work that usually needs three or four separate desktop packages.

Fire Protection · NFPA-13

Fire-Ready

A looped fire ring main with a Q=K√P sprinkler grid: over-deliver the design density, clear the 7-psi minimum, and prove the demand point sits under the supply curve.

Project Console · Earned Value

One Project, Every Function

A 12-document carbonation-pilot register run end-to-end: paste it from Excel, let IFR/IFA/IFC status gates drive the percent, pull open HAZOP actions onto the Gantt, and read an earned-value S-curve replayed from an append-only change log.

41.9%
earned value rolled up from 12 weighted documents — every percent traced to a status gate

Honest by design

Real solves, stated limits, no marketing fiction.

Every number on these pages is a verified production-solve result. Where a result is a risk indicator rather than an achievable value — or where a fluid is handled by a standalone calculator rather than the network solver — we say so on the page. One model solves one fluid regime; cushioning and the unprotected danger case are two distinct runs. We would rather earn your trust than win the demo.
