Aspherix® and CFDEM®coupling allow for the high-fidelity simulation of complex sediment transport and wave-induced erosion processes. By precisely modeling fluid-particle interactions and multi-phase hydrodynamics, our solution tracks exact particle displacement and beach morphology changes under dynamic wave loads. This integrated workflow captures critical physical behaviors like sub-surface movement and localized structural wear without relying on empirical guesswork. Ultimately, this predictive digital twin empowers principal engineers to design resilient coastal infrastructure, mitigate environmental impact, and significantly reduce long-term maintenance costs.
