Just to double-check, I used another software CASTEP but that resulted in a reasonable geometry (with respect to the experimental structure). This is not for a comparison between cp2k and CASTEP but I would like to learn where I was wrong in the cp2k input description/model. The input geometry and the cut-off value (925) for both cp2k and CASTEP are the same but CASTEP used PBESol where cp2k used PBE. In both cases, the Hexagonal symmetry was fixed.</div><div dir="ltr"><br clear="none"></div><div dir="ltr">I know both packages are completely different in various means, especially pseudopotentials and plane waves, etc. </div><div dir="ltr"><br clear="none"></div><div dir="ltr">Any help would be highly appreciated. </div><div dir="ltr"><br clear="none"></div><div dir="ltr">P.S.
