<div>I'm running a vc-relax calculation on a six-element alloy. First I used the following list as pseudo potentials: </div><div><br></div><div><div>Al 27.D0 Al.pz-vbc.UPF</div><div>Ti 48.D0 Ti.pz-sp-van_ak.UPF</div>
<div>Cr 52.D0 Cr.pbe-mt_fhi.UPF</div><div>Fe 56.D0 Fe.pz-nd-rrkjus.UPF</div><div>Co 59.D0 Co.pbe-mt_fhi.UPF</div><div>Ni 59.D0 Ni.rel-pbe-nd-rrkjus.UPF</div><div><br></div><div>But it crushed and said " Error in routine set_dft_value(1): two conflicting matching values". Then I used a new list of pseudo potentials as the following: </div>
</div><div><br></div></div><div style="font-family:arial,sans-serif;font-size:13px"><div>Al 27.D0 Al.pz-vbc.UPF</div><div>Ti 48.D0 Ti.pz-sp-van_ak.UPF</div><div>Cr 52.D0 Cr.pz-hgh.UPF</div><div>Fe 56.D0 Fe.pz-nd-rrkjus.UPF</div>
<div>Co 59.D0 Co.pz-nd-rrkjus.UPF</div><div>Ni 59.D0 Ni.pz-sp-hgh.UPF</div></div><div style="font-family:arial,sans-serif;font-size:13px"><br></div><div style="font-family:arial,sans-serif;font-size:13px">Then it runs. Is it because that in the second time, the pseudo potentials I used are of the same kind? If so why is it necessary in a DFT calculation? </div>
