Re: [Wien] Structure optimization of a monoclinic lattice
I cannot remember for sure, but I think WIEN2k might need you to use 14_P21/a spacegroup setting in StructGen. It looks like your struct file in StructGen has 14_P21/c. Have you perhaps went to: https://materialsproject.org/materials/mp-7944/# Click CIF next to Final Structure and click on Symmetrized to download NaSb_mp-7944_symmetrized.cif Then, did you go to: https://jp-minerals.org/vesta/en/download.html Download VESTA. Then, open VESTA 3.5.7 and drag/drop NaSb_mp-7944_symmetrized.cif into it. Click Edit -> Edit Data -> Unit Cell Select "P 21/a (Unique axis c)" Click Apply, then click OK Click File -> Export Data and Save as NaSb.cif Finally, get NaSb.struct using: cif2struct NaSb.cif If you have not done that, maybe give that a try. That should be because sgroup requires that you use the "14 [P 21/c] [unique axis c] [cell choice 1]" setting. The sgroup program uses coded names according to the International Tables 1992 [ http://www.mail-archive.com/wien%40zeus.theochem.tuwien.ac.at/msg08153.html ]. I believe "14 [P 21/c] [unique axis c] [cell choice 1]" may be equivalent to "P 21/a (Unique axis c)".

[Wien] Structure optimization of a monoclinic lattice
Dear Wien2k users, I am trying to do ABC & Gamma optimization of a monoclinic lattice. At the cif file of the structure, the angle Beta was greater than 90 while Alpha & Gamma were 90 degree. To incorporate with the usual formalism of wien 2k I have changed the angle Beta to Gamma & Gamma to Beta. I have also alternate b to c & c to b & also y-coordinates to z coordinates & z coordinates to y-coordinates. However, with this changed struct file when I saved the structure (file attached) the warning is coming as " space group is not consistent with cell parameters" & I not able to move further. Any response will be appreciated.
