Multiple Application Areas

FLOW-3D HYDRO is used in numerous areas of water and environmental technology:

Hydropower

FLOW-3D HYDRO allows engineers to accurately analyze complex flow phenomena in weirs, spillways, inlet and outlet structures, capturing energy dissipation, air entrainment, cavitation, and sediment transport processes.

Ports & Coasts

Detailed 3D models capture waves, tides, and sediment transport, enabling realistic assessment and planning of erosion protection, coastal infrastructure, and environmental mitigation measures.

Air Entrainment

Powered by physics-based models, FLOW-3D HYDRO accurately captures air entrainment, bubble dynamics, and multiphase flows to deliver deep insight into turbulent water–air interactions.

Marine Engineering

FLOW-3D HYDRO simulates complex interactions between structures, waves, and flows under tsunami and wave loading, identifying critical hydrodynamic effects on offshore installations and marine components.

Hydropower and Spillways

  • 3D simulation of free-surface flows for optimizing inlets and outlets, weirs and spillway gates
  • Proof of operational safety and performance, including rating curves as well as velocity and pressure distribution
  • Assessment of extreme and transient processes, e.g. sluice gate movements or flood events
  • Support in the constructive design of the energy conversion to optimize efficiency and protect against erosion and cavitation

Ports & Costal Engineering

  • Simulation of waves, currents, and water level variations in harbor basins and near-coastal areas
  • Assessment of the performance and safety of access channels, entrance/exits, quayy structures, and coastal protection works
  • Investigation of sediment transport, siltation, and dredging stategies to maintain navigable waterways
  • Analysis of wave loads on structures (breakwaters, revetments) and optimization of proposed design alternatives

Rivers & Environment

  • Modeling of complex free-surface flows in natural channels (meanders, islands, groynes, hydraulic structures)
  • Analysis of sediment transport, erosion and deposition, and riverbed evolution to support the evaluation of mitigation measures
  • Simulation of water quality as well as tracer, pollutant, and temperature transport for environmental impact assessments and permitting processes
  • Support for ecological studies, including habitat allocation, environmental flows (residual flows), fish passage, and the planning and optimization of fish ladders and downstream fish passage facilities

Water & Wastewater

  • Detailed CFD analysis of basins, channels, and distributors to ensure uniform flow patterns and residence times
  • Assessment of sedimentation, resuspension, and short-circuiting flows to support structural optimization of facilities
  • Simulation of mixing and aeration processes to enhance process reliability and energy efficiency
  • Support for the design and verification of new and existing structures (inlet structures, outlets, weirs) based on realistic 3D flow fields

General Hydraulic Engineering & Hydraulics

FLOW-3D HYDRO is purpose-built for CFD applications where precision matters

  • High-performance free-surface simulation (TruVOF) for real hydraulic processes
  • Comprehensive physics modules: Sediment/Morphology, Turbulence, Moving Bodies, Structural Interaction
  • Intuitive workflow with geometry import, mesh creation, simulation and evaluation
