FLOW-3D HYDRO can be used as an advanced modeling tool when 3D non-hydrostatic modeling capabilities are necessary to provide a greater degree of accuracy and model resolution. Typical modeling applications are related to small dams/infrastructure, transportation hydraulics, complex 3D river hydraulics, thermally buoyant plumes, outfalls and contaminant transport. A key feature of FLOW-3D HYDRO is a shallow water model that can be dynamically linked with the full 3D model. This capability allows users to extend the model domains for multiscale modeling applications to maximize computational efficiency with required model resolution. FLOW-3D HYDRO also includes additional features and advanced physics specifically geared toward the river and environmental application area.

FLOW-3D HYDRO simulation of a free discharge outfall. Complex free surfaces are easily and accurately simulated in FLOW-3D HYDRO using the volume of fluid (VOF) method.
Fish screens or exclusions are designed to prevent the movement of aquatic organisms into hydroelectric, irrigation or other types of water withdrawal structures. FLOW-3D HYDRO is used by engineers to test different designs for efficacy and adherence to regulatory requirements for the hydraulic conditions near the screen, including limitations on the approach velocity, which should prevent fish from impinging on the screen, and sweeping velocities, which should prevent debris build-up.
This FLOW-3D HYDRO simulation shows sediment scour formation and a dune formation for a 2D case. The FLOW-3D HYDRO results are validated against the Chatterjee experiments. Learn more about the Sediment Transport model.
Rendering of a FLOW-3D HYDRO dense jet simulation, this visualization uses volume thresholds in FLOW-3D POST, Flow Science’s new postprocessor available across all FLOW-3D products. Learn more about FLOW-3D POST‘s visualization and analysis capabilities.
Development of a hydraulic jump simulated with FLOW-3D HYDRO. The top view is a ray-traced rendering of the flow; the bottom view, a 2D slice of the velocity field. This simulation was postprocessed with FLOW-3D POST, our new postprocessor for visualization and analysis across FLOW-3D products.
Hydraulic jumps such as the one shown in this simulation can be engineered to provide energy dissipation at dam outfalls and other structures which would be at risk due to the kinetic energy of the flow. This simulation was created in FLOW-3D HYDRO and postprocessed using FLOW-3D POST‘s ray tracing capabilities.
This FLOW-3D HYDRO simulation uses the Hybrid 3d/Shallow Water model to better understand and more efficiently model bridge hydraulics. The simulation fully couples the 3D model with a 2D shallow water model together in one run. The surrounding areas to the bridge were modelled in full 3D, while the upstream and downstream areas of the river were modelled using a 2D shallow water model.
