Dear all,<br><br>I used to submit an manuscript to a specialized journal about chemistry and physics. The referees suggested me to perform some molecular dynamics. I now agree with the referees that the molecular dynamics is essential to confirm the configurations from pw.x. But I have little experience in First principle molecular dynamic, but I have a good impression of classical MD. So I think I could accomplish it with some learning from more experienced people. Following the excellent manual provided by the website, I try to use cp.x code to perform molecular dynamics on my systems. Now it is running... <br>
<br>But I have a question about the option "nr1b, nr2b, nr3b" in &SYSTEM namelist. Could you please tell me something more about it?<br>How to determine the proper value for different systems. Do you think it could greatly increase the computational time consumption if the value is not properly set?<br>
I want to calculate a system of 147 atoms with 48 [TiO2] units and a water molecule. And following the autopilot example, I set these three value to 20 repectively. do you think it is reasonable for this system?<br>If not, could you please tell me something about how to set it properly. <br>
<br>thank you for reading.<br><br>any suggestion is deeply appreciated. Thank you in advance.<br><br>best wishes,<br><br>vega <br clear="all"><br>-- <br>==================================================================================<br>
