Pair distribution function (pair_distribution)

Here we provide data suitable to test the programs pair_distribution.f90 and pair_distribution.py, which are available in the Examples repository. The file pair_distribution_data.zip contains a set of 500 configurations of N=256 Lennard-Jones atoms, cut (but not shifted) at R_c=2.5σ, at the usual state point ρ=0.75, T=1.0. The interval between configurations was 100 MC sweeps. For more details about the programs, and a plot of the results from this data set, refer to the Fortran GUIDE or the Python GUIDE.

Interface pair correlation function (grint)

Here we provide data suitable to test the program grint.f90, which is available in the Examples repository. The file grint_data.zip contains a set of 100 configurations from a simulation of a system of N=10000 atoms, interacting through the Lennard-Jones potential cut (but not shifted) at R_c=2.5σ, in a cubic box of side 30σ, at a temperature T=0.90. For this system, ρ_G ≈ 0.024, ρ_L ≈ 0.713. Output files from grint.f90 with default parameters are also provided. The slices for z>0 (z₁ in the liquid) and c<0 (z₂ further in the liquid) most resemble homogeneous liquid pair distribution functions. Those with z<0, c>0, where both particles are on the gas side, are the most noisy and show least structure. For more details about the program, refer to the Fortran GUIDE.
