void peclet::dem::Simulation::setSleeping ( bool  enabled,
float  threshold_scale = 2.0f,
int  consecutive = 64,
float  wake_scale = 40.0f 
)
inline

Island sleeping / freezing (single-GPU statics, default ON; PECLET_DEM_SLEEP=0 disables).

A REAL body whose linear AND angular motion stays below scale x the resting floor (2 dt |g|) for K substeps while grounded is put to sleep: velocity zeroed, integration skipped, and a manifold whose BOTH endpoints are asleep (a static wall counts) is excluded from the colouring / sweeps / multilevel hierarchy — so a settled bed collapses to the broad/narrow-phase floor. A sleeper keeps a small POSITIVE effective inverse mass in the solve (sleepImmovableFrac x its own; heavy but not perfectly rigid), so an awake body wedged between sleepers relieves against them instead of the PGS normal impulse diverging; its velocity is re-zeroed each substep so no momentum accumulates. It wakes only when disturbed (fast approaching neighbour, contact-set change, moving wall). Requires gravity on and no external (CFD-DEM drag) force; inert under MPI. PECLET_DEM_SLEEP overrides at startup.

◆ setVerletSkin()

void peclet::dem::Simulation::setVerletSkin ( float  skin_frac)
inline

Verlet-cached impulse broadphase (single-GPU, non-periodic; default OFF).

skin_frac is the broadphase-skin fraction of the max grain radius: the ArborX rebuild is skipped while no particle has moved more than skin/2, so between rebuilds the candidate list is a superset and the narrowphase yields identical contacts. Composes with sleeping (a frozen bed never rebuilds).
