我建了一个高分子无定型胞,并对他进行退火处理,但是经常遇到这个问题“Dynamics calculation - Aborting dynamics.
An unphysical integration step (>100 Angstroms) has been detected.
Try relaxing the structure with geometry optimization, reducing the time step,
reducing the temperature or a combination of these.”Time step 是按着文献来的,常用的1 fs,结构优化也重复做了很多次了,还是会报出这个问题,请教一下大佬,这是什么原因导致的呢?一般怎么处理的啊
