Uploaded July 2026 | Updated September 2026, 1 week ago

FLOW-3D HYDRO is a fully 3D CFD simulation tool that allows for highly accurate and detailed prediction of the hydraulic conditions critical for successful fish passage design. In this circular fishway pool concept, the user can simulate the full 3D flow field for high-resolution velocity, depth, and turbulence characteristics. FLOW-3D HYDRO improves on traditional 1D and 2D approaches, allowing higher accuracy and flexibility in analyzing project-based designs. FLOW-3D HYDRO users can model more complex flow features and evaluate hydraulic conditions encountered by the fish, providing valuable insights for various stakeholders in the fish passage industry.

$Powder Directed Energy Deposition Additive Manufacturing - Bead Geometry Modelling | FLOW-3D AM In this simulation, the Computational Fluid Dynamics (CFD) model of FLOW-3D AM was used to predict the morphology of the bead in DED Additive Manufacturing. The simulation captures the dilution of newly deposited material into the previous layer or substrate. Moreover, the temperature, solid fraction, and velocity inside the melt pool are calculated which gives a detailed picture of the bead formation in this metal 3D printing process.

$Melt Pool Simulation of Overhang Dross in Laser Powder Bed Fusion (LPBF) | FLOW-3D AM This laser powder bed fusion (LPBF) simulation animation shows 3 melt tracks as the laser beam approaches a down-facing overhang surface that runs parallel to the laser motion. The lack of structural support beneath the overhang surface causes the melt pool to sink lower than its neighboring layers, producing an effect called Dross. Naturally, dross formation causes dimensional inaccuracy, high surface roughness and also adversely affects the mechanical properties of printed components. FLOW-3D AM is used to quantify process parameters to reduce defects like dross.
