A I know, the cooling rate depends how long the time I run the simulation. Thus, if the temperature decreases from 4000k to 0K in 400ps, the fooling rate will be 40K/ps, while running in 2000ps, the cooling rate would be 2k/ps, right? no. you are discounting the …
Tīmeklis2015. gada 16. apr. · due to new features in LAMMPS, initialization has become quite complex and it appears that in your specific case of granular media simulation, some setup is missing. this can often be worked around by inserting a "run 0" statement, which enforces executing a full setup. axel. sjplimp October 10, 2024, 5:23am #3 Tīmeklis2024. gada 14. sept. · 出现这个错误的直接原因是体系中某些原子的近邻数超过了2000个（除非你使用neigh_modify命令增加了允许的近邻数），而导致这个错误的可能因素有： 初始结构有问题，比如原子分布过于密集。 这种情况在一开始就会出错。 截断半径设置的太大了，比如大于10A。 可以通过命令neighbor，减小截断半径来解决。 在 …
