Dear Elliot, Now I _think_ that I know what your problem is. For similar systems I use 'ibrav = 4', hexagonal cell that is (one needs to specify "a" and "c", the angle is automatically the 120 degrees), and I either use "alat" or "crystal" as the unit for the atomic coordinates: The former

Dear Elliot, Sorry, but what do you mean with "straight"? I could not open the picture, it was apparently an absolute path. Do you mean that you want it to be aligned along the z axis? If you give us a further hint, probably we can help you. Greetings from Zurich, apsi -=

Dear Apsi, I might be getting the description wrong but what I want to do is to place an adsorbate(Carbon monoxide) on the surface and run a calculation to get the energy involved. And the literature I have seen, which is guiding me, has the crystal cell looking perfectly like a well-oriented-

Hello, I have a slab surface of nickel 111 with the cubic crystal cell slanted. nickel-111-3x3surf.png Can i make it sit straight? I want to orient it to sit straight. How do i do that please? Thank you. Happy Holidays Thank you. -- Elliot S. Menkah Research Student - Computational Chem
