在做小分子蛋白复合物模拟时，调电荷之后mdrun,报错:
Step -1:
The charge group starting at atom 1342 moved than the distance allowed by the domain decomposition (3.417050) in direction Y
distance out of cell 2552.957462
Old coordinates: 3.610 2.696 2.358
New coordinates: 1610.154 2556.375 5.610
Old cell boundaries in direction Y: 0.000 3.417
New cell boundaries in direction Y: 0.000 3.417

-------------------------------------------------------
Program mdrun, VERSION 4.5.5
Source code file: domdec.c, line: 4124

Fatal error:
A charge group moved too far between two domain decomposition steps
This usually means that your system is not well equilibrated

请问这怎么解决呀？？？

调电荷是指加过离子？

就是按照流程，体系中有非平衡电荷，需要加离子平衡体系
