This page collects animations from various simulations based on NetDEM.
Granular mixing of spheres.
Random packing of mixed types of particles, including poly-super-ellipsoid, poly-super-quadrics, spherical harmonics, level set, polyhedron, etc.
Nut sliding on bolt without frition and damping, where the nut and bolt is modeled with polyhdral particles in DEM.
Packing and compression of deformable particles, with particle deformation solved by finite element method and particle contacts solved by signed distance field approach.
Triaxial compression of irregular-shaped particles that are represented by spherical harmonics.
Random packing of generaly irregular-shaped particles, where the contacts are handled by neurual networks.
Debris flow simulation with spheres and triangles (using contact-area-weighted contact forces). Note this example is intended to demonstrate the capability of NetDEM but have not been calibrated to reassemble a real debris flow.
Dam break and waves strike onto irregular-shaped particle assembly, a demonstrative example of integrating with OpenFOAM for coupled CFD-DEM simulation.
Column collapsing of irregular-shaped particles that are represented by spherical harmonics.
Particle curshing simuated with coupled DEM-peridigm, where level set-based domain splitting appraoch is employed for fragments reconstruction.
Membrane tensiling and twisting, simulated with finite element and neo-hookean model.
