Modules

contact

Fused Hertz-Mindlin contact force: computes normal and tangential forces in a single pair loop, eliminating redundant shared computation (distance, material lookups, Hertz stiffness, normal force magnitude).

granular_temp

normal

rotational

tangential

Structs

GranularDefaultPlugins

Default DEM granular physics plugin group.

Constants

LARGE_OVERLAP_WARN_THRESHOLD

Large overlap warning threshold (ratio of distance to sum of radii)

MAX_OVERLAP_WARNINGS

Max overlap warnings per step before panic

SQRT_5_3

√(5/3) — viscoelastic damping coefficient

TANGENTIAL_EPSILON

Epsilon to avoid division by zero in tangential force
