[lammps-users] The ParaGrandMC code

Dear lammps researchers,
I would like to quote the MC code of "Relationship between Grain Boundary segregation and grain Boundary Diffusion in Cu-Ag Alloys "in the title of this article.The network address of this MC code is https://software.nasa.gov/software/
LAR-18773-1.This can only be downloaded by local LAMMPS researchers in the US.I wonder if he is a local RESEARCHER of LAMMPS in America. Could you help me download this MC code!
Looking forward to your help!
