| Parameter | Value / Finding | | :--- | :--- | | Alloy | A356 (Al-Si-Mg) | | Mold | Sand + chill | | Crack observed (physical) | Web area near central chill (hot tear) | | Flow-3D CAST prediction | RDG index = 1.4 in same location | | Strain rate at coherency | $3.2 \times 10^-3 s^-1$ (above critical $1.5\times 10^-3$) | | Mitigation simulation (increase chill radius) | RDG index dropped to 0.8 → No crack predicted → Confirmed by trial |
Users typically follow an objective-based modeling workflow:
: FLOW-3D CAST includes a finite element-based thermal stress evolution (TSE) model. This allows you to predict precisely where internal stresses will occur and how a casting will distort during cooling. Deformation Tracking i--- Flow 3d Cast Advanced Crack
: Identifies areas of shrinkage porosity.
The advanced version of I-Flow 3D Cast offers several key features that set it apart from other casting simulation software: | Parameter | Value / Finding | |
: Dedicated environments streamline the setup for complex geometries like V8 engine blocks or giga-castings. These workspaces include presets for vents and chills that can be optimized to reduce stress-induced defects. Thermal Die Cycling
is an industry-leading Computational Fluid Dynamics (CFD) software developed by Flow Science. It is widely used by foundry engineers to simulate metal casting processes, predict defects, and optimize tool designs. Within industrial engineering, "Advanced Crack" refers to the software's highly specialized thermo-mechanical stress modules used to predict hot tearing, structural cracking, and residual distortion in cast components. The advanced version of I-Flow 3D Cast offers
