Dear Mr. Hammand, Could you please give some(1 or 2) examples to illustrate the difference, or just paste the format of Avorgado, so that we would be easier to reach the question?Thanks. Hsin-Ying Lu 在 2024年2月20日 星期二 上午06:03:43 [GMT+8], Microsoft.com team 寫道: Dear HusakThanks a lot for

Dear Tarek Hammad You can easily build a molecular structure with the Avogadro GUI https://avogadro.cc/ and preoptimize it with its built-in force field. If your molecule has a lot of conformers/rotamers you should find and sort them to identify the global minimum. An excellent and easy to

Dear Tarek A very elegant way to get molecular coordinates is via SMILES (symbolic molecular specs) and OpenBabel. SMILES:  https://en.wikipedia.org/wiki/Simplified_molecular-input_line-entry_system OpenBabel: converts SMILES string to 3D coordinates http://openbabel.org/ (on Debian-based linux

[QE-users] incorporation of one into other

2024-02-20 Thread Gulshan Kumar via users
Hi all, I want to know some basic details about the incorporation of one atom at another atom position (*to create input file)*; let say I want to incorporate in the cubic phase with Pm3m space group, the Sr2+/Bi3+ ions occupy 1(a) sites at (0, 0, 0), Si4+/Fe2+/Cu5+ ions occupy 1(b) sites at (1/2,
