Delft3D Flexible Mesh Suite
The Delft3D Flexible Mesh Suite (Delft3D FM) is the successor of the structured Delft3D 4 Suite. Like Delft3D 4, the Delft3D FM Suite can simulate storm surges, hurricanes, tsunamis, detailed flows and water levels, waves, sediment transport and morphology, water quality and ecology, and is capable of handling the interactions between these processes. The suite is designed for use by domain experts and non-experts alike, which may range from consultants and engineers or contractors, to regulators and government officials, all of whom are active in one or more of the stages of the design, implementation and management cycle.
Within the Delft-FEWS operational framework, Delft3D FM can offer 24/7 forecasts. Forecasts, predictions and uncertainties can easily be visualized on dedicated websites, using the Delta Viewer technology. To get the most out of simulation results, Deltares offers 3D visualization services: the results of Delft3D FM in a 3D interactive serious gaming enviroment. Designed for policymakers, Delft3D FM is also available on a Touch Table for interactive modelling with all the stakeholders.
The key component of Delft3D FM is the D-Flow Flexible Mesh (D-Flow FM) engine for hydrodynamical simulations on unstructured grids in 1D-2D-3D. D-Flow FM is the successor of Delft3D-FLOW and SOBEK-FLOW. It is the result of five years of research funded by Deltares and the Dutch Ministry of Infrastructure and Environment.
Some areas of applications
- Tide and wind-driven flow;
- Drying and flooding of inter-tidal flats;
- Density driven flow due to density gradients of non-uniform temperature and salinity concentration distributions;
- Horizontal transport of matter on large and small scales;
- Hydrodynamic impact of engineering works such as land reclamation, breakwaters and dikes;
- Thermal recirculation of cooling water discharges from a powerplant.
Some of the typical key features of Delft3D FM are:
- the suite gives direct access to state-of-the-art process knowledge, accumulated and developed at one of the world’s most renowned hydraulic institutes;
- the Graphical User Interface (GUI), based on Delta Shell, is one of the most user-friendly in the market:
- Central map with spatial editor
- Customizable and dockable window views
- Connectivity to online data bases
- Batch running through Python scripting interfaces
- all modules show a high degree of integration and interoperability.
Delft3D FM allows you to simulate the interaction of water, sediment, ecology, and water quality in time and space. The suite is mostly used for the modelling of natural environments like coastal, estuarine, lakes and river areas, but it is equally suitable for more artificial environments like harbours, locks, urban areas, etc. Delft3D FM consists of a number of well-tested and validated modules, which are linked to and integrated with each other.

The 2019.01 (November 2018) release was the first General Availability (GA) release for 2D morphology.
Early 2019, an important improvement was implemented for correct sediment mass balances. This change unfortunately later turned out to have negative impact on the robustness for some models, leading to worse model results. This behavior is present in the releases 2019.02, 2019.04 and 2020.01 (2019.03 was never released).
In the upcoming 2020.02 release, this issue has been fixed. The results of model runs are now again comparable to the ones with the 2019.01 release, also including the mass balance improvements as well as the restored robustness. This 2020.02 release is expected to be made available at the end of December 2019.
We noticed that sources and sinks are neglected in the file-based coupling to D-Water Quality when using D-Flow Flexible Mesh.
This issue (UNST-2686) will be solved in the upcoming Delft3D FM Suite 2020.01 (September 2019) release.
When performing steady state simulations, restarting D-Flow FM should give the same steady state answer. This is not the case (UNST-2717).
Frequently asked questions
This message indicates an issue with the Delft3D Flexible Mesh license file or license manager. Please ensure the DS_Flex License manager and your license file have been installed.
Yes, there is.
Our development team is working hard to make all components of Delft3D FM available in open source, both computational engines and Graphical User Interface components (GUI).
The key component of Delft3D FM is the D-Flow Flexible Mesh (D-Flow FM) engine for hydrodynamical simulations on unstructured grids in 1D-2D-3D. As long as the 1D-2D-3D architecture of D-Flow FM is subject to change, the access to the D-Flow FM code will be limited to a small group of Partners in Development. We anticipate having D-Flow FM in open source for everyone in 2019, but it could become 2020.
Yes, this is possible.
For this, Deltares has introduced the Partner in Development / Beta Testing Programme.
- Provide external users with the possibility to gain experience with the software
- Testing of the software by pilot users
- What are typical problems that users encounter?
- Identifying bugs in software
- How can software be further improved?
- Gain insight in the performance and accuracy of the software
- Push the developments of the software
Each pilot user is appointed a Delft3D Flexible Mesh ambassador from Deltares, who can assist the pilot user during the duration of the beta testing project. The interaction between pilot user and ambassador varies, but meetings, Skype meetings / GoToMeetings, email and calling are all possible. To ensure good modelling practice, each ambassador will review the existing models in collaboration with the pilot user at the start of the project and at various key moments during the project.
Please send us more information about your topics of interest for beta testing and in which R&D or other projects we could join forces?
Delft3D FM is supported on Microsoft Windows:
- Windows 10 64bits
Delft3D FM support on Linux is available under our beta testing conditions and within our research programme only. For our beta testing – research programme, please contact firstname.lastname@example.org.
The advised minimum requirements:
