WebLAMMPS computes this by taking the maximum bond length, multiplying by the number of bonds in the interaction (e.g. 3 for a dihedral) and adding a small amount of stretch. ... Minimization requires that neigh_modify settings be delay = 0, every = 1, check = yes. Web甚至超出lammps预定的极限就会溢出。unit real情况下，skin一般2-3，配合使用 neigh_modify delay 5就可以了。如果使用neigh_modify delay 3 还有很高比例的Dangerous builds，应该是你的积分步长太大，应适当减小积分步长。
