Delft3D Flexible Mesh Suite
The Delft3D Flexible Mesh Suite (Delft3D FM) is the successor of the structured Delft3D 4.02 Suite. Like Delft3D 4.02, 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. Designed for policymakers, Delft3D FM is 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.
Delft3D Flexible Mesh Suite 2017
The launch of the Delft3D Flexible Mesh Suite 2016 (Delft3D FM) took place during the Delft Software Days (DSD-INT 2015) at the Symposium ‘Next Generation Hydro Software (NGHS)’ on Tuesday, 3 November 2015.
For now, only the D-Flow Flexible Mesh module (2D) of the Delft3D FM Suite, as the successor of the Delft3D-FLOW module, is fully validated and supported within the Delft3D Service Packages.
Both the 1D and the 3D part of the D-Flow Flexible Mesh module and all other modules and their interactions, such as D-Waves, D-Real Time Control, D-Water Quality, D-Particle Tracking and D-Morphology, are available
The upcoming Delft3D FM Suite 2018 will include:
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.
How to get Delft3D Flexible Mesh (Delft3D FM)?
The latest fully validated release is Delft3D Flexible Mesh Suite 2017. This version is available via our Delft3D Service Packages. You can easily order one of our service packages via email@example.com and then download the software via our Download portal.
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 D-Water Quality module, as the successor of Delft3D-WAQ, simulates the far- and mid-field water and sediment quality due to a variety of transport and water quality processes. To accommodate these, it includes several advection diffusion solvers and an extensive...
The D-Particle Tracking module, as the successor of the short-term, near-field water quality module called Delft3D-PART, estimates the dynamic, spatial (on a sub-grid scale) concentration distribution of individual particles by following their tracks in time. The waste substances may be conservative...
The D-Morphology module, as the successor of Delft3D-MOR and SOBEK-MOR, computes sediment transport (both suspended and bed total load) and morphological changes for an arbitrary number of cohesive and non-cohesive fractions. Both currents and waves act as driving forces and...

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 late 2017, but it could become 2018/2019.
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 both Microsoft Windows and Linux.
- Windows 7 64bits
- Windows 10
Support on Linux is only available under our beta testing conditions and within our research programme only. For our beta testing – research programme, please contact firstname.lastname@example.org.
