Overview

A lot of questions can be answered in 1D long before committing to 3D CFD. Is this pump head sufficient? Is flow evenly distributed across branches? Will the cooling system cavitate at peak load? Flomaster assembles the system from pumps, valves, pipes and heat exchangers and answers in minutes.

It suits system-level sizing and matching especially well, because changing one parameter re-solves immediately — engineers can sweep dozens of combinations at concept stage instead of waiting overnight for a 3D run. Use 1D for the system scheme and 3D CFD for local detail; together they are far more productive than either alone.

Positioning

1D thermo-fluid system simulation

Dimensionality

1D system level

Analysis types

Steady / transient / two-phase

Modelling

Graphical component assembly

Typical industries

HVAC, marine, energy, automotive thermal management

Key capabilities

Component-based modelling

Drag and drop pumps, valves, fittings and heat exchangers. No meshing.

Fast solving

1D solutions are extremely quick, so parameter sweeps and scheme comparisons finish in minutes.

Steady and transient

Steady-state plus transient events such as water hammer, start-up and valve actuation.

Flow and pressure distribution

Clear branch flow, pressure drop and velocity output that pinpoints bottlenecks fast.

Coupling with 3D CFD

Feed 1D results to 3D as boundary conditions, or calibrate 1D components from 3D results.

Pump and valve sizing

Built-in component libraries that can be modelled from vendor catalogue data.

What it delivers

Evaluate system matching at concept stage and avoid late redesign
Fast enough to compare dozens of schemes in a day
Pump and valve sizing becomes evidence-based rather than “go one size up to be safe”
Transient events such as water hammer and cavitation surface early
Complements 3D CFD, raising overall simulation throughput
