http://www.52souji.net/lammps-command-lattice.html Webb25 juni 2024 · The "Lost atoms" error typically happens when huge forces blow up an MD calculation. This is also the problem here: The main issue are the units. The input parameters for reax force fields are given in "real" units by default. Unless they are converted real units have to be used in the lammps input file.
