The integrity of hydraulic structures is constantly tested by environmental and operational factors. When these factors combine—high-velocity water flow and thermal stress (the "hot" scenario)—cracks can quickly evolve into critical failures.

provides an industry-leading computational fluid dynamics (CFD) framework to model these complex systems. It features a robust multi-physics suite capable of coupling advanced free-surface tracking with heat transfer. This capability is critical for simulating thermal cracking (hot cracking) in structural components exposed to high-velocity, thermally varied fluid zones.

In industries like metal casting, welding, nuclear reactor cooling, or geothermal systems, high-temperature fluids interact with solid structures. “Hot cracking” (solidification cracking) occurs during the final stage of solidification when insufficient liquid feed meets thermal contraction stresses. FLOW-3D HYDRO, while primarily known for free-surface flows, can be extended to simulate conditions leading to thermal cracking. flow 3d hydro crack hot

If your report pertains to manufacturing rather than civil engineering, it likely refers to the Hot Tearing (Cracking) defect analysis found in the CAST workspace. Basic Model Setup | FLOW-3D HYDRO

Rather than distorting the mesh to fit curved structural walls, the FAVOR™ method embeds complex solid geometries into a regular, structured Cartesian grid. By calculating exactly how much volume and area of a cell is occupied by a solid obstacle, it eliminates grid-alignment errors. This enables highly accurate calculation of fluid-to-solid boundary layer gradients, which are critical for predicting localized thermal shocks. 3.
