3d Cfd Modeling With Flow-3d Hydro

FLOW-3D HYDRO is an advanced 3D CFD modeling software that has been used extensively for 40+ years in applications related to the design and analysis of dams/spillways, conveyance infrastructure, water treatment and river hydraulics. Core capabilities include a fully 3D non-hydrostatic solver with specialization in free surface flow applications. Additional multi-physics capabilities include a fully mobile bed 3D sediment transport model, non-Newtonian flow fluid properties, air entrainment, heat transfer, and combined 2D/3D simulation domains.

Fully 3D CFD simulation software can provide valuable insights for testing design options, helping to reduce complexity and focus efforts on optimized solutions in situations where conventional numerical and physical modeling approaches are limited. This computer modeling demonstration will first provide a general overview of 3D CFD fundamentals and how it is different from other types of simulation and analysis tools. We will then discuss key technical features of the numerical model and demonstrate how it is used to go from problem statement to solution for a case study of the Garrison Dam spillway. This will include an analysis of modeling approaches, model setup workflows, post-processing, and results validation. We will also explore the use of workflow automation and optimization tools.
