Aspherix® and CFDEM®coupling allow for the high-fidelity simulation of dynamic riverbed erosion and sediment transport. By integrating a coupled Volume-of-Fluid (VoF) and Discrete Element Method (DEM) approach, the software precisely captures the transient hydrodynamic forces acting on individual sediment particles. This predictive digital twin workflow enables engineers to model multi-phase fluid-particle interactions and track changing bed morphology under varied flow rates without relying on simplified empirical models. Ultimately, this advanced simulation framework empowers principal engineers to safeguard hydraulic infrastructure, design resilient river management strategies, and minimize environmental impact.
