[交流] 【求助】出错了已有2人参与

Range checking error:
Explanation: During neighborsearching, we assign each particle to a grid
based on its coordinates. If your system contains collisions or parameter
errors that give particles very high velocities you might end up with some
coordinates being +-Infinity or NaN (not-a-number). Obviously, we cannot
put these on a grid, so this is usually where we detect those errors.
Make sure your system is properly energy-minimized and that the potential
energy seems reasonable before trying again.

Variable ci has value -2147483648. It should have been within [ 0 .. 1331 ]

这是我在做分子动力学模拟时出现的错误提示,我想问一下这是什么意思,应该怎么解决,望高手能够指点几招,谢谢

这是我的格子中的粒子数增多后,能量最小化时出现的,也有的在跑动力学出现,一直不知道哪里出错了。我还一直不明白的是为什么格子中的粒子数少时就给算,粒子数多了就出现这个问题呢,希望高手能指点一下,谢谢
