Newton-Raphson Pipe Network Solver
Primary solver handles unlimited looped, gridded, and tree pipe networks simultaneously. Converges to 0.001 L/min residual — well within AS2118 tolerances.

Hydraulics
Industry-leading hydraulic solvers
From simple tree systems to complex looped networks, FireCalc Pro handles every topology with certified solver algorithms.
Hazen-Williams & Darcy-Weisbach
Choose the friction loss method appropriate for your system. Hazen-Williams for sprinkler and hydrant systems; Darcy-Weisbach for water mist per AS4587.
Friction Methods
Hardy Cross Fallback
When primary convergence is difficult, the solver falls back to Hardy Cross iteration automatically — no manual intervention required.

Collaboration
Designed for engineering teams
FireCalc Pro is built for multi-engineer firms — share calculations, review designs, and submit consistent reports.
Role-Based Access Control
Owner, admin, and engineer roles. Company accounts with domain enforcement prevent external access to sensitive project data.
Role Access
Threaded Project Comments
Leave inline comments on any project. Tag colleagues, resolve threads, and keep a full audit trail of design decisions.
