Before these (SCF and DOS) calculations, I want to do a “vc-relax” calculation but when I start “vc-relax” using SCAN, I get an error that says like, stress calculation is not possible for spin polarized SCAN function. So seems like I have to do “vc-relax” without SCAN and after “vc-relax” I can use SCAN function for SCF and DOS calculation. Since output of “vc-relax” is sensitive to pseudopotential and exchange function type, what type of pseudopotential and exchange function I should use for “vc-relax” in this case or is there any way to perform spin polarized “vc-relax” calculations using SCAN? I am using QE version 6.3<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks,<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Shoaib Muhammad<o:p></o:p></p><p class=MsoNormal>Department of Energy Science<o:p></o:p></p><p class=MsoNormal>Sungkyunkwan University,<o:p></o:p></p><p class=MsoNormal>Suwon, Korea<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
