Enable the Viscous Flow , Granular/Proppant Transport , and Deflectable Solid/FSI models.

Flow-3D Hydro is not generic CFD software. It was built for free-surface flows. When addressing the problem, three specific features make it indispensable: flow 3d hydro crack top

(using the Volume of Fluid or VOF method), it handles complex physical phenomena that intersect with structural integrity: Fluid-Structure Interaction (FSI): Enable the Viscous Flow , Granular/Proppant Transport ,

Crucially for "crack top" analysis, the FDEM-flow3D model does not just simulate existing fractures. It can reproduce the within a crack, model the crack initiation and propagation , and account for fluid loss during the fracturing process [16†L6-L11][19†L19-L21]. This level of fidelity is essential for understanding how cracks begin at a structural surface and propagate through materials, posing a risk to structural integrity. When addressing the problem, three specific features make

Refine the mesh locally at the crest. Flow-3D allows nesting of fine mesh blocks (e.g., 2mm resolution) inside a coarse mesh (50mm resolution). This captures the velocity gradient inside the crack without exploding computational cost.

Because high-velocity water flowing over concrete can exploit minor surface imperfections, analyzing crack flow—the intrusion, uplift, and cavitation of water inside a crack—is essential to preventing structural failures. Understanding "Crack Top" and Uplift Dynamics in Hydraulics
