The mean-field Poisson-Boltzmann and its linearized Debye-Huckel equation for the distribution of counterions in a two-dimensional hexagonal lattice of DNA cylinder is solved numerically. The results are compared to previously published counterion density obtained using Grand Canonical Monte-Carlo simulation. It is shown that mean-field results agrees well at small counterion valence and concentration (large interhelices distance). However, at high concentration or high counterion valence, the strong correlation among counterions cannot be ignored. This is inline with such calculation for single DNA or dimeric DNA systems.
