[CASTEP] 计算晶格常数

计算晶格常数

请问CASTEP里面的Dynamic能不能算晶体高温下的晶格常数?多谢指教!

基于能量泛函的第一性原理的计算好像一般都不算太高温度的,算0K的较多吧

二楼的好像正确,

In principle, it is ok. As you said, you need run DFT-MD.
You need run NPT for a long time, at least several thounds steps, then you get the averaged lattice constant.

请问计算完了要怎么算平均值,里面有什么快的方法吗

you can just average the value that you get. Sure, you can ignore some data for the beginnning.
