Classes
class	peclet::dem::Simulation
	Host-facing facade with std::vector setters/getters (binding-agnostic). More...

Namespaces
namespace	peclet
namespace	peclet::dem

Functions
int	peclet::dem::readInt (Kokkos::View< int, CpMem > v)
float	peclet::dem::maxOwnedRadius (const Particles &P)
	Largest effective particle radius over the owned set (= max scale × globalScale, growth included).
int	peclet::dem::findCollisionsGrow (Particles &P, float margin)
	Broad phase with an automatically-grown pair buffer.
void	peclet::dem::demStep (Particles &P)
	One full XPBD DEM substep over the particle SoA (mirrors simulation.cpp Simulation::step()).
float	peclet::dem::computeOverlapsKokkos (Particles &P)
	Max pair interpenetration on the committed state (faithful to CUDA Simulation::compute_overlaps): copy committed pos/quat into the predicted buffers, regenerate the periodic ghosts from that state, then run the same broad/narrow phase as demStep and return the recorded max overlap.

Detailed Description

dem — portable (Kokkos) Simulation facade: the dem flip's host-facing driver.

Owns a peclet::dem::Particles SoA and runs the full XPBD DEM step by composing the ported kernels in the simulation.cpp step() order. Exposes a small std::vector-based API (binding-agnostic) so a pybind module can drive it from Python (set/get arrays, step). Sphere shapes + analytic planes for now.
