The multisclae pair (pair_multiscale.h, pair_multiscale.cpp) has been implemented in LAMMPS. Compile: cp pair_multiscale.h pair_multiscale.cpp ~/lammps-31Mar17/src make ubuntu Usage: Example: pair_style multiscale pair_coeff * * Al.eam.alloy Al.agni Al Al Al 10 100 5 6 1 1 2 3 4 5 6 7 8 9 10 10 coefficients: 1: filename and path for EAM-FS potential 2: filename and path for AGNI potential 3-5: element name 6: Nevery, the CS parameter is computed every Nevery timesteps 7: Nfreq, the CS parameters are averaged every Nfreq timesteps based on the calculated CS parameter in the preceding portion of the simulation every Nevery timesteps. 8: Threshold value, the atoms in simulation are divided into two sub-regions based on the comparison between averaged CS parameters and the threshold value option-coeff: 9: The thickness of the transition region 10: Whether to dump the atomic sub-regions to atomic types.
