[求助] LAMMPS入门报错求指导!急!!

各位大佬:

LAMMPS in文件设置如下图所示,报错ERROR: All pair coeffs are not set (../pair.cpp:254)。

想用两种reaxff力场描述混合体系。其中 reaxff_JPCL力场描述mass 1-6,即S O C F Li H。用ffield.reax.ZnOH力场描述mass 7-9 Zn H O。请大佬指正如何设置好in文件?感谢感谢。

Your simulation uses code contributions which should be cited:

- pair reaxff command:

@Article{Aktulga12,
author = {H. M. Aktulga, J. C. Fogarty, S. A. Pandit, A. Y. Grama},
title = {Parallel reactive molecular dynamics: Numerical methods and algorithmic techniques},
journal = {Parallel Computing},
year =    2012,
volume =  38,
pages =   {245--259}
}

- fix qeq/reaxff command:

@Article{Aktulga12,
author = {H. M. Aktulga, J. C. Fogarty, S. A. Pandit, A. Y. Grama},
title = {Parallel reactive molecular dynamics: Numerical methods and algorithmic techniques},

reaxff不支持这么用,你得找一个包含所有元素的力场。
