Minimum displacement magnitude

Hi everyone

In computer simulations one necessarily has to work on a discrete lattice, rather than treating variables as continuous. Is this implemented for particle displacements in LAMMPS? So is there a minimum particle displacement below which it is disregarded and flushed to 0?

Best wishes,

Jonas

there is no specific need to implement this. the "lattice" is
determined by the "granularity" of floating point math.

LAMMPS uses double precision floating point math throughout with a few
specific exceptions (explicitly requested single precision FFTs and
GPU/OpenCL/CUDA/XeonPhi with single precision kernels).
