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 deformable domains.
Objective:
Simulate how granular materials (like powders, sand, or pellets) pack into or against deformable structures and analyze:
- Particle packing and flow behavior
- Deformation and stress in the structure
- Influence of structural deformation on particle
