FluidFlow FAQ
FluidFlow is pipe network analysis software for engineers who design, size, troubleshoot, and optimize fluid piping systems. It performs steady-state hydraulic analysis of liquid, gas, two-phase, slurry, and non-Newtonian flows — calculating pressure drop, flow distribution, temperature profiles, and equipment operating points across complete pipe networks.
FluidFlow supports 5 flow types in a single software: (1) Single-phase liquid (incompressible), (2) Gas (real compressible), (3) Two-phase liquid-gas, (4) Settling and non-settling slurry, (5) Non-Newtonian flow. No module switching required — the software automatically detects phase based on operating conditions.
Yes. FluidFlow offers a free 14‑day trial with full professional functionality, including all simulation modules and advanced tools. The trial includes sample projects to help you start immediately, plus direct technical support via chat and email.
It is used in oil & gas, mining, chemical processing, power generation, water supply & treatment, shipbuilding, pharmaceuticals, food & beverage, LNG, and more — across over 68 countries and 1,000+ companies. Any industry with fluids flowing through closed piping can benefit from FluidFlow.
Per CoMo Industrial Engineering, FluidFlow saves 80% of design time compared to spreadsheets. Unlike Excel, it automatically solves complex branched networks, includes a built‑in database of 1,200+ fluids and 800+ equipment items, sizes pumps/valves/pipes automatically, and incorporates real pump performance curves. Calculation methods are validated through 300+ QA models and 40 years of engineering practice.
FluidFlow adheres to: ANSI/ISA‑75.01.01 (control valve Cv/Kv calculation), ISO 5167‑1:2003 (orifice plates, Venturi tubes, flow nozzles), API 520 Part 1 (safety relief valve sizing), and ISO 4126 (overpressure protection devices). Flite Software NI Ltd maintains ISO 9001:2008 certification.
Most engineers become proficient within a few hours and build their first pipe network model in minutes. Free on‑demand training covers liquid and gas module theory. The unified interface eliminates the need to learn multiple separate software packages.
