Delft3D 4 and Delft3D FM

Delft3D FM Suite as the new integrated water modelling and simulation suite

Deltares is working to integrate and improve our hydro software. Important technological innovations make up the new Delft3D Flexible Mesh Suite (Delft3D FM) for integral simulations. Delft3D FM combines proven technology from the hydrodynamic engines of Delft3D 4 and SOBEK 2 and adds flexible administration. The new, advanced software will allow water managers and modelers to do their work better and faster. For the presentation “Delft3D FM Suite – Key advantages“, click here.

Delft3D 4 functionality in Delft3D FM Suite

The Delft3D FM Suite will be the aggregated successor of the structured Delft3D 4 Suite. Delft3D FM is set up within the Delta Shell Framework, providing additional functionality, extensive compatibility and an intuitive user interface.
