Here using LAMMPS molecular dynamics (MD) software, we simulate polymer translocation in 2 dimensions. We do the simulations for weak and moderate forces and different pore diameters. Our results show that in both non-equilibrium and equilibrium initial conditions, translocation time will always increase by increasing binding energy and or increasing pore diameter. Moreover, scaling exponent of time versus force is -0.9531 in accordance to our predecessors. The comparison between equilibrium and non- equilibrium initial condition shows that the translocation time is very sensitive to the initial condition. Translocation time of the relaxed polymers for interaction energy of 8𝑘𝐵 𝑇 is smaller from the non- equilibrium case even in the small energy of 1𝑘𝐵 𝑇. Moreover, our simulation results show that the translocation velocity decrease by increasing the nanopore diameter from 3𝜎 to 5𝜎, where 𝜎 is the size of a monomer.
