Aspherix® and CFDEM®coupling allow for the high-fidelity simulation of dynamic debris flow and structural clogging at hydraulic control barriers. By utilizing the advanced multisphere method in Aspherix® to accurately represent various complex geometries of floating log wood, the digital twin framework captures realistic structural entanglement. On the fluid side, an integrated Volume-of-Fluid (VoF) solver in CFDEM®coupling models the underlying transient water flow, creating a fully coupled hydro-mechanical feedback loop. Ultimately, this predictive workflow delivers critical insight into blockage thresholds, enabling principal engineers to optimize weir design geometries, mitigate flooding risks, and safeguard downstream infrastructure reliability.
