Particle insertion mechanisms: packing to a target density/count, rate-controlled streams and regions, lattice/mesh-defined volumes, and run-termination tied to fill/settling state rather than a fixed time.
auto_filling_region/— combined pack + stream insertion into a VTK-mesh-defined volume, terminating automatically once the region reads as full (simulate mode until_filled).insertion_and_growing_particles/— undersized particles packed at low density, then grown in place up to a target volume fraction.insertion_dense_packing/— a dense poly-disperse pack placed directly in one step via the dense/experimental packing generator.insert_rate_in_region/— particles fed at a controlled mass rate into a fixed region above a chute.insert_stream/— continuous particle stream through a planar mesh face, including a restart/resume variant.region_mesh_vtk/— an insertion volume defined by a tetrahedralized VTK mesh, filled with a regular lattice of particles instead of a random pack.stop_when_settling_is_done/— a single pack insertion run until the bed kinematically settles (simulate mode until_settled), instead of a fixed target time.
