  Graphynes are a family of porous carbon allotropes that are viewed as ideal
2D nanofilters. In this present work, the authors have modified the Improved
Lennard-Jones (ILJ) semi-empirical potential used in the previous works by
adding the induction term (iind) to define the full interaction. The evaluation
of the computational cost was done comparing ILJ vs ILJ-iind and analyzing the
adsorption of 1 gas (CO2) and a small mixture of gases containing CO2, N2 and
H2O. The computational time of the different calculations is compared and
possible improvements of the potential models are discussed.
