Respected sir,<br>
<br>
<br>
I have a R-3m compound.While making super cell its <br>
symmetry is lowered to P1.So while initialising the X symmetry it <br>
shows some warning that the sgroup is hexagonal and you have to change <br>
it to the appropriate s group.If i neglect this and run SCF cycle <br>
whether it shows any error.I request you kindly to look into this. I <br>
have also attached the struct file with this.I extended the super cell <br>
in x direction(2:1:1).When i run AFM calculation i am getting <br>
ghostband error.<br>
<br>
<br>
l2main' - QTL-B.GT.15., Ghostbands, check scf files.This error message <br>
in uplapw2.error<br>
When i checked the Scf files it shows to change the energy values for <br>
an atom with a particular L.When i try this then the error shift to <br>
other atom.So is this a problem due to my structure file.How can i <br>
resolve this error?<br>
<br>
with regards<br>
