<font>嗨,我有一个类似的问题。我想在MD中建立一个恒定的电场,然后研究电场对结构的影响。我使用了 &EFIELD 部分,即非周期边界。我想知道这是否是正确的做法。</font><br /><font>谢谢。</font><br /><br /><div class="gmail_quote"><div dir="auto" class="gmail_attr">On Tuesday, October 18, 2022 at 1:51:02 AM UTC+8 Matt Watkins wrote:<br/></div><blockquote class="gmail_quote" style="margin: 0 0 0 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">Hi, no I'm afraid that only works with real time propagation TDDFT.<div>To approximately get a time dependent field I maybe suggest a normal MD run with the PERIODIC_EFIELD.
