TUFLOW Product Bundle Discount FAQs

TUFLOW Product Bundling FAQs

TUFLOW comprises two hydrodynamic modelling engines designed to meet a wide range of hydraulic and environmental assessment needs:

  • TUFLOW Classic / HPC is commonly used for short term hydraulic simulation such as water levels, depths, velocities and hazard.
  • TUFLOW FV is a flexible mesh solver well suited to longer term studies and more complex environmental processes including water quality, sediment transport or 3D flows.

As environmental assessment requirements continue to broaden, organisations are increasingly expected to simulate water quality, sediment transport, particle movement and other processes in addition to traditional hydraulics. Demand for this capability has increased rapidly over the past 18 to 24 months. In response, TUFLOW is introducing a revised product bundle discount structure that makes it easier for users to access both engines.

Product Bundle Discount Structure Overview

To support organisations that wish to use both modelling engines, TUFLOW now offers a 100 percent engine licence purchase discount when an organisation already holds one engine type and wishes to obtain the other.

Each organisation is assessed based on the total value of its maintained engine licences. Two branches are defined:

  • Primary Branch is the engine type with the greater total maintained value, or the one that will have the greater value once a quotation is complete.
  • Secondary Branch is eligible for a 100 percent discount on engine licence purchases, up to the number of seats in the Primary Branch.
Examples

Organisations With Only One Engine Type

A consultancy with a Network 5 Classic / HPC licence may obtain up to Network 5 FV at a 100 percent purchase discount. They may choose FV Network 1, 2, 3, 4 or 5 at no cost.

The same applies in reverse for organisations that currently use only FV.

Organisations With Both Engine Types

An organisation has: Local 6 Classic / HPC and Local 2 TUFLOW FV

Classic / HPC has the greater total value, so would be classified as the Primary Branch. FV is classified as the Secondary branch 

The organisation may acquire up to Local 6 FV engine licences at no purchase cost, allowing them to increase FV capacity from Local 2 to Local 6.

If FV were the larger pool, Classic / HPC would instead receive the discount.

Costs and Maintenance

While Secondary Branch engine purchases receive a 100 percent discount, annual maintenance fees still apply. This is because at TUFLOW we prioritise providing the highest quality support and software.  Annual Maintenance is 15 percent of the engine licence list price and supports research and development, software updates and ongoing customer support

The discount applies to engine licences only and does not extend to module licences.

Environmental Modules Streamlined

To support more advanced environmental modelling, TUFLOW is simplifying its environmental module structure. The Advection Dispersion (AD) module is discontinued as a standalone product. From 2026 onward, AD functionality is included at no extra cost with any environmental module, including: 3D, Water Quality, Sediment Transport, Particle Tracking and CATCH.

Free Upgrade for AD Licence Holders

Organisations that currently hold AD licences (Classic / HPC or FV) will receive a free upgrade to one environmental module. One upgrade is provided per AD licence. The TUFLOW sales team will be contacting all eligible organisations over the coming month to discuss what free module upgrade they would like, and to process associated licence updates. 

Shared Module Use Between Engines

The TUFLOW CATCH (including AD functionality) and GPU module can be shared between Classic / HPC and FV when using TUFLOW releases from 2025.0.0 onward. For this module sharing to function, all licences associated with the model simulation must be hosted on the same licence type (i.e. all on a local hardware dongle/s, software lock/s or cloud licence/s).

    Training and Expertise Support

    The TUFLOW team offers comprehensive training to assist Classic / HPC modellers transitioning to advanced environmental modelling in FV. Training can include:

    • Mesh generation.
    • Water quality and sediment transport workflows.
    • Multi session programs with time for practical application.
    • Peer review of models, reports and modelling workflows.

    Training can be tailored to project specific needs.
