我的模型是从MS软件中导出来的，力场设置的是cvff，用LAMMPS中的msi2lmp工具导出data文件。data文件我也认真看了，没有错误。但是我在提交LAMMPS运算时出现了如下情况： ------------------------------------------------------------------------------------------------------ LAMMPS (22 Mar 2013) Scanning data file ... 25 = max angles/atom 88 = max dihedrals/atom Reading data file ... orthogonal box = (0 0 0) to (10.4507 6.0874 4.752) 4 by 2 by 2 MPI processor grid 28 atoms 116 angles 272 dihedrals Finding 1-2 1-3 1-4 neighbors ... 0 = max # of 1-2 neighbors 0 = max # of 1-3 neighbors 0 = max # of 1-4 neighbors 1 = max # of special neighbors 4 atoms in group 1 16 atoms in group 2 4 atoms in group 3 4 atoms in group 4 Replicating atoms ... orthogonal box = (0 0 0) to (31.3521 18.2622 14.256) 4 by 2 by 2 MPI processor grid 756 atoms 3132 angles 7344 dihedrals Finding 1-2 1-3 1-4 neighbors ... 0 = max # of 1-2 neighbors 0 = max # of 1-3 neighbors 0 = max # of 1-4 neighbors 1 = max # of special neighbors WARNING: Resetting reneighboring criteria during minimization (min.cpp:173) Ewald initialization ...
