Core/shell partner atom not found是什么原因?
|
||
|
大家好!我用lammps計(jì)算BaTiO3材料,用的core/shell模型。參考了手冊(cè)的in文件寫法,出現(xiàn)了錯(cuò)誤“Core/shell partner atom not found”。手冊(cè)的解釋是Could not find one of the atoms in the bond pair. 我一直沒想明白是哪里出了問題。尋求大家的幫助,十分感激。 data文件是 LAMMPS Description 1250 atoms 625 bonds 6 atom types 3 bond types 0 20.0500011445000 xlo xhi 0 20.0500011445000 ylo yhi 0 20.0500011445000 zlo zhi Masses 1 47.867 2 0.0001 3 137.327 4 0.0001 5 15.9994 6 0.0001 Atoms 1 1 1 4.7600 2.0050 2.0050 2.0050 2 1 2 -1.5800 2.5050 2.5050 2.5050 3 2 3 5.6200 0.0000 0.0000 0.0000 4 2 4 -3.7600 0.5000 0.5000 0.5000 5 3 5 0.9100 0.0000 2.0050 2.0050 6 3 6 -2.5900 0.5000 2.5050 2.5050 (...)
