Veevee is a molecular and electronic structure editing and analysis tool. Below is a very short introduction to get you up to speed using Veevee.

View mode of Veevee


Veevee allows you to view, edit and analyse the molecular structure and/or electron density of VASP calculations. For these three purposes, we have a "view", "edit" and "Electron density analysis" mode. The view mode is the default mode. To go to the edit mode, you can use the TAB key. For going to the electron density mode, use the F1 key.

Opening files

To open a file, click on the folder open icon or use the short key CTRL+O. A file browser pop-up will appear allowing you to the select a structure. Alternatively, you can drag and drop files into the Veevee window from the Windows explorer.

Moving or rotating atoms

Make sure you are in edit mode (use the TAB key to go there). To move or rotate atoms, you first select the atoms by either clicking on them using the right mouse button, or by selecting them by dragging a rectangle over them (press b (box) for that). Veevee uses two selection buffers, the first selection buffer indicates which atoms should be transformed and the second selection buffer is used as a reference for this transformation. To move the selected atoms, press g (grab). You can constrain this movement by pressing x, y or z to constrain the movement to a particular axis. Alternatively, you can press f to constrain the movement to a vector that is constructed from the first and second selection buffers. Press l to restore unconstrained movement.

To rotate the selection, press r (rotate). Again, you can constrain the rotation by pressing x, y or z to constrain to a particular Cartesian axis. Alternatively, you can constrain the movement around a rotation axis constructed from the centers of the first and second selection buffer by pressing f (focus) or around a rotation axis constructed by the two atoms inside the second selection buffer (only if there only two atoms inside that buffer) by pressing l (line).

Saving files

To save a file, make sure you are in view mode. Press the disk icon or use the short key CTRL+S. You can select between various file formats.
