DEM–FEA Coupled Simulation for Granular Packing
Simulating granular packing using DEM and FEA is a powerful way to analyze how granular materials interact with solid structures-especially when both the particle dynamics and the deformability of the structure are important. Coupling DEM and FEA allows for detailed, high-fidelity simulations of granular packing in…
