General Questions and Answers / LDOS from VASP ProjectOnSite

« on: April 28, 2026, 03:07 »

Dear all, I am still trying to visualize VASP PDOS (or LDOS). I calculate them in VASP, but when I try visualizing, I am getting the message attached, e.g "LDOS requires one of the following projections: ProjectOnSite, ProjectonShellBySite, ProjectIOnOrbitalsBySite.

I am confused - did I not specify something in VASP - I did LORBIT=11 which calculates LDOS. What is QATK asking or telling me here, how do I visualize these LDOS?

thank you

Jonas

General Questions and Answers / VASP PDOS from PROCAR

« on: February 1, 2026, 21:28 »

Dear all, I apologize if this has been asked. I am trying to visualize VASP calculate TDOS and PDOS, DOSCAR give me only TDOS, ir I click on PROCAR it returns be an error message below. I presume I need PROCAR of decomposed PDOS and indeed that file is large, soit  it contains info obtained with VASP LORBIT=11, I was wondering how can I display those

General Questions and Answers / equilibrate water molecules in a box

« on: May 13, 2020, 04:30 »

Dear all, what would be a quick way using Windows version of QuantumATK Q-2019.12-SP1 to construct a box, fill it it water molecules and run some MD simulation to obtain a low energy structure for DFT optimization? The building of bulk water by hand is tedious and naturally it's not correct bonding anyways

General Questions and Answers / templates in structure viewer

« on: May 13, 2020, 04:27 »

I was wondering if there is an option to save the layout in the viewer so the next time crystal/surface slab is open it would display the same color scheme/ball stick/etc. I could not find one and it would be very handy so there Is no need every time set the settings by hand

thank you
