<table cellspacing="0" cellpadding="0" border="0" ><tr><td valign="top" style="font: inherit;"><br>Dear All, <br>Good day to you all. <br>When I was working on TiO2 .scf.in, I have succeded in getting convergency for celldium 1 (i.e. a) and celldium 3 which is c/a. I am now on TiO2.nscf.in. The system is complaining about my nbnd., calculation. I am not even too sure of my high symmetric values of my K points. Please assist me am still fresh in the use of quantum espresso.<br><br>&control<br> calculation = 'nscf',<br> restart_mode='from_scratch',<br> prefix='TiO2'<br> pseudo_dir='/home/funmilayo/espresso-4.2.1/pseudo',<br> outdir='./',<br> tprnfor = .true.<br> tstress = .true.<br>/<br>&system<br> ibrav=6, celldm(1)= 8.9300,celldm(3)= 0.6943, nspin =2, starting_magnetization(1) = 0.7,<br> nat=3, ntyp=2,occupations='smearing', nbnd =16.
