Thank you so much, <span style="orphans: 2; widows: 2; line-height: 1.5;">Kawamura and Paolo. So this is a bug to be fixed in 6.2, right?</span><div><span style="orphans: 2; widows: 2; line-height: 1.5;"><br></span></div><div><span style="orphans: 2; widows: 2; line-height: 1.5;">Another thing I don't understand is that why we need </span>"tetrahedral-opt" instead of "tetrahedra"? As I tested, "tetrahedra" works for no SOC pdos projection. “tetrahedra-opt" is just not mentioned in input_projwfc.html. And also according to the html file, "The tetrahedron method is presently not implemented" for pdos, and smearing is always implemented. Then, why does "occupation=tetrahedra" matters? </div><div><br></div><div>And what is more, is <span style="line-height: 1.5; orphans: 2; widows: 2;"> </span><span style="line-height: 1.5;">"tetrahedral-opt"</span><span style="line-height: 1.5;"> better in any case than "tetrahedra" in terms of efficiency and quality? Should we always use </span><span style="line-height: 1.5;">"tetrahedral-opt" in the future?</span></div><!--😀-->
