5 exciting features coming in Flood Modeller version 5.1

Flood Modeller 5.0, the next generation of Jacobs’ industry-leading flood modelling software, was unveiled earlier this year and we’re already preparing for the release of version 5.1 in September 2021.


Flood Modeller 5.1 brings a number of new features and capabilities, and we wanted to share a few of the things we’ve been working on!


Quick overview | What’s coming soon?

  1. Enhanced 1D urban solver

  2. New 2D GPU solver

  3. Faster and more flexible plotting capabilities

  4. Enhanced hydrological tools

  5. New licence management tools


Enhanced 1D urban solver

Seamlessly build run and analyse all within Flood Modeller – no need to use multiple software packages.

In version 5.1, we will be adding model build capabilities to enhance our recently released 1D urban solver. You will be able to quickly and accurately build your urban drainage system directly within Flood Modeller's powerful user interface, without the need for third-party software.


This latest enhancement has simplified the modelling of multiple sources of flooding, allowing you to obtain a detailed and integrated understanding of flood risk in urban areas. It removes the need for different software packages - saving you time and money.

New 2D GPU solver

Speed up your simulations with our super-fast GPU solver. We have taken our existing solver and made it run on NVIDIA GPU hardware enabling you to complete your work significantly quicker than before.


Use the new GPU solver to reduce the time it takes to run your existing models or build larger and more detailed models to get a more detailed understanding of flooding without worrying about long run times.


As we are using our existing solver, the new 2D GPU solver allows you to retain the same high levels of detail and accuracy, when compared to the standard 2D ADI and TVD solvers.


Using Flood Modeller’s 2D GPU solver, you can also benefit from our user-friendly GIS interface which is proven to help users better understand their models, as well as having access to Flood Cloud’s powerful NVIDIA Tesla V100 GPU hardware.


Faster and more flexible plotting capabilities

We have made several key improvements and added new features to make it quicker and easier to load results and process large data files.


The plotting tools are designed to improve your understanding of flood risk, particularly variations in flow or stage at multiple locations within your models together with variations between different simulations.


All plotting tools have been enhanced to operate much quicker. You will have the ability to upload a CSV file as an alternative for plotting additional data to compare to your model results. We’ve added new chart toolbars to provide easier editing and customisation of your charts (to make them report-ready).


The improvements we have made simplify your data handling, save you time when plotting data, and give you the ability to extract the information most important to you with less effort.


Enhanced hydrological tools

In Flood Modeller 5.1, we have introduced some new options that provide users with additional ways to incorporate flow time series data when running your 1D simulations.


You can now read flow-time series directly from a CSV data file to include in your simulation, which can detail a range of different storm events and locations and then just pick which to use at runtime.


In addition to being able to use a more generic “free” format you will also be able to take output from the Irish FSU hydrological data portal - we’ve also included a direct link to this portal from the Flood Modeller interface.


In your 1D river simulation file you can detail alternative storm durations, return period settings and scale factors to apply to any hydrological boundaries included in your network. This will avoid the need to create a separate event data file for each return period etc. Thus, making it quicker and easier to set up and run a range of different scenarios.


Finally, we have updated our ReFH2 boundary unit to incorporate the latest release of ReFH2 (v2.3), including not only the revised methodology, but also enabling the ability for the user to adjust parameters, such as ARF, SCF, etc.


New licence management tools

We are committed to improving Flood Modeller and enabling users make the most of the licences that have. That’s why, following customer feedback, we will be introducing a new licence management feature for our network licence users. This is designed to give you the ability to downgrade or release a ‘checked out’ licence. This will simplify the process when sharing licences between computers and/or different users.

If you’re new to Flood Modeller and interested in using the software, please get in touch. We would be happy to recommend the most appropriate and cost-effective licensing solution. We offer monthly, annual and long-term licensing options and two editions of the software, all of which can be tailored to meet your project requirements.
