  The large-scale structure of the Universe is distributed in a cosmic web.
Studying the distribution and clustering of dark matter particles and halos may
open up a new horizon for studying the physics of the dark Universe. In this
work, we investigate the nearest neighbour statistics and spherical contact
function in cosmological models with massive neutrinos. For this task, we use
the relativistic N-body code, gevolution and study particle snapshots at three
different redshifts. In each snapshot, we find the halos and evaluate the
letter functions for them. We show that a generic behaviour can be found in the
nearest neighbour, $G(r)$, and spherical contact functions, $F(r)$, which makes
these statistics promising tools to constrain the total neutrino mass.
