The per-contact overlap-projection body lives in PositionContactSweep so the colored launch loop and the fused colour sweep (solver_fused.hpp) share it verbatim: solveOne(idx) must only run concurrently on contacts that are body-disjoint within one launch (a colour class). More...

Detailed Description

The per-contact overlap-projection body lives in PositionContactSweep so the colored launch loop and the fused colour sweep (solver_fused.hpp) share it verbatim: solveOne(idx) must only run concurrently on contacts that are body-disjoint within one launch (a colour class).

solveOne()

void peclet::dem::PositionContactSweep::solveOne ( int  u ) const

inline

One work item: every contact of position unit u, sequentially in ascending contact index (a pair's points are a serial Gauss-Seidel sweep inside one item; §4.3).

A one-point unit is today's per-contact arithmetic on today's contact.
