simple a question. But I have a few doubts on minimization. I would be extremely

optimization. <o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face="Times New Roman"><span style='font-size:
11.0pt'>I am working on a system with a monoclinic lattice. I am a bit
disappointed that my queries on monoclinic lattice have not been answered
before even when it has neither been addressed before nor been discussed.
Hopefully this question would be answered. <o:p></o:p></span></font></p>

case by choosing Option 7, can we say with authority that <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face="Times New Roman"><span style='font-size:
11.0pt'>1. Internal coordinates minimization of monoclinic case (with 18 atoms
per unit cell) keeping the lattice parameters same would be enough to know the
total energy. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face="Times New Roman"><span style='font-size:
11.0pt'>In any case, after lapw_mini, the optimized coordinates are saved in
the case.struct, so running the SCf again would give the optimized total
energy. <o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face="Times New Roman"><span style='font-size:
