Dear PWSCF users,<br> <div id=":67" class="ii gt"> I am using
PWSCF for BaTiO3 thin films calculation, I just wanted to visualize the
(110) surface of the same by xcrysden. I am pasting the input PWSCF
file for the same, the problem is my system is monoclinic but xcrysden
is showing it to be cubic, may be I am doing some mistake. Please
anybody help me out to fix the problem. The calcualtin is for one layer.<br>
