<div dir="ltr"><div> Hello experts,</div><div><br></div><div>I want to apply vdw and dipole correction on my heterogeneous cell with Cr2O3 and graphene stacked along with 13 A of vacuum.</div><div>I am employing vdw_corr="XDM" with my system and want to employ dipole correction too.</div><div>I am using USPP with revPBE XC functional.</div><div>
<div><br></div><div>I used the values of xdm_a1 and xdm_a2 from the list mentioned but under PAW pseudopotential. There was no mention of the USPP.</div>
</div><div><br></div><div>In dipole correction I do not want any external electric field, So I used</div><div>eamp = 0.000</div><div><br></div><div>I want to know how to determine the value for other parameters like, edir, emaxpos and eopreg?</div><div>I should mention again, I do not want to apply any external field. <br></div><div><br></div><div>
I am attaching my input file <br></div><div><br></div><div>Can someone please give some insight over this?</div><div><br></div><div>Please also mention if you find other glitches like choice of vdw correction or pseudopotential, etc. <br></div><div><br></div><div>Thank you in advance.</div><div><br></div><div>Regards</div><div>Yuvam Bhateja<br></div></div>
