—to simulate complex phenomena such as 3D hydraulic fracturing and structural cracking. Understanding FDEM-flow3D and Hydraulic Fracturing
The findings showed that 3D modeling is essential for capturing the complex 3D behavior of the flood wave, especially when the dam fails due to hydraulic overtopping. Conclusion
Simulating hydraulic fracturing involves modeling the injection of fluid into rock to create fractures. Flow 3D can model the fluid dynamics of this process. Here are general steps to approach this simulation:

FLOW-3D HYDRO is specifically tailored for civil and environmental engineering, allowing engineers to visualize these transient events that are impossible to accurately predict using 1D or 2D models. 1. Advanced Free Surface Modeling
In the context of dams or spillways, analyzing "cracks" typically involves investigating how water pressure and flow interact with structural flaws. FLOW-3D HYDRO facilitates this through several key capabilities: DiVA portal Fluid-Structure Interaction (FSI):

Engineers frequently use the term "Crack Top" to describe the initial phase of an overtopping failure. Unlike a sudden catastrophic collapse, many embankment dams begin to fail because a small weakness develops along the or the downstream face. This could be a tension crack caused by settlement, a poorly compacted zone, or a localized "nick point" where water first starts to spill.
Most CFD solvers struggle with the air-water interface, blurring the boundary. Flow-3D’s TruVOF (Volume of Fluid) method preserves the sharp discontinuity at the water surface. For a crack top simulation, this means the model accurately predicts the exact point where flow detaches from the crest, the thickness of the falling nappe, and the air entrainment rate.
When water meets concrete, nature doesn’t blink—but concrete does. Over time, hydraulic structures like dam crests, spillway chutes, and levee tops develop cracks. These aren't just cosmetic blemishes. A crack at the of a hydraulic structure can trigger uplift pressure, internal erosion (piping), and eventual failure. Flow 3D can model the fluid dynamics of this process
Unlike conventional methods, 3D CFD calculates all three components of fluid velocity without the need for depth-averaged simplifications. This level of detail is particularly crucial for modeling the strong vertical flow accelerations found near weirs, spillways, and within cracks themselves [12†L8-L11]. As a complete 3D CFD modeling solution powered by an industry-leading solver engine, FLOW-3D HYDRO is designed to put these exceptional simulation capabilities into the hands of engineers and water specialists tackling 21st-century challenges in water resource management [10†L2-L7].
The is the most vulnerable structural millimeter on any dam or spillway. It is where physics—separation, cavitation, entrainment, and jacking—conspires to destroy infrastructure. Traditional models cannot see it. Generic CFD tools blur the interface. Only Flow-3D Hydro provides the fidelity, speed, and validated physics to predict whether that crack will remain stable or trigger a failure cascade.
