Four folders are included: doc: documentation of COMB implementation src: source codes for COMBs potentials: parameter sets for COMB3 force field ffield.comb3: standard parameter set lib.comb3: special parameter set for carbon-hydrogen-oxygen force fields. Need to be copied to working directory example: an application of COMB3. Results are shown in log.lammps. Downloaded the latest LAMMPS from LAMMPS website copy COMBs source codes inside 'src' folder to LAMMPS 'src' folder then make For usage of fix_qeq/comb or fix_qeq/ecomb, please read the readme.fixqeq.txt and readme.ecomb.txt. Use the parameter files (ffield.comb3 and lib.comb3) from folder 'potentials'. Do NOT use these two files from the same foldername in LAMMPS.
