FlowNetMaster | Thermal-Hydraulic System Design & Simulation Software

Simulation has revolutionized the design and optimization of thermal-fluidic systems over the past decades by minimizing costly experimental testing and accelerating time-to-operation. FlowNetMaster offers a fast, reliable and high-fidelity simulation environment. The program allows users to define a system, sub-system hierarchy thus removing clutter and making their models readable and easy-to-maintain. FlowNetMaster offers a collaborative working hub for a team of engineers through distributed version control. This feature of FlowNetMaster is entirely built with engineering teams in mind and aims at boosting productivity.


  • Steady-state and transient simulation

  • Demonstration of thermo-hydraulic principles
  • In-class lectures and term-project assignments

This demo video illustrates the key features of FlowNetMaster. FlowNetMaster offers an easy-to-use drag-and-drops user interface wherein engineers can build their models and run simulations without the need to know a specific programming or a modeling language. No code writing is involved. FlowNetMaster includes a number of steady state and transient solvers to obtain physical solution.

FlowNetMaster has a built-in database for standard components. Users can also add their custom components to their own database. For example users can import an image file of a pump characteristic curves from a manufacturer’s product catalogue or datasheet and digitize this image using our friendly and intuitive interface and then save this pump to their database for later use within their models.

FlowNetMaster also offers basic data visualization tools (graphing, model coloring, vector indicators for flow direction etc.) and data export to third party software for further manipulation and data reduction.

One of the features of FlowNetMaster that practising engineers will come to appreciate the most is the built-in pdf report generation feature indeed. Custom reports can be produced only with a few mouse clicks after solving the model.
