Here I am attaching a smaller simulation with the same problem.

c_displace_4 is the LAMMPS supplied displacement magnitude; the fourth element of the vector computed by compute displace/atom.
DisplacementMagnitude is the OVITO displacement magnitude.

Both are at the same timestep and use the same reference configuration.

They're a bit too large for an attachment. I placed them in my Public Dropbox.

Sorry about that. Please see attached.

Please see the screenshot below:

This is a 2 nm radius x 8 nm long cylinder. A uniaxial tension simulation was performed in LAMMPS using metal units so I assume the distance units Ovito is using are Angstroms. At timestep 1000 (0.0001 strain), Ovito is displaying 0.4% of the atoms have a DisplacementMagnitude > 100. If that is 10 nm this is impossible.

What is going on here? Thank you.

Can Ovito be run without the GUI (and without calling QT5) by scripting and having it dump images?

EDIT: From the manual: Note that render() returns a QImage, giving you the possibility to manipulate the rendered picture before saving it to disk.
So I'm guessing that even dumping an image requires QT5? Unless OVITO supports another alternative.

Getting the following error trying to run the ovito-2.9.0 binary on Linux

[VGL] ERROR: Could not load symbol "xcb_poll_for_queued_event"
[VGL]    /usr/lib64/libxcb.so.1: undefined symbol: xcb_poll_for_queued_event

This is on an HPC system that I do not have admin access to and I am using a VNC client.

EDIT: I spoke to the HPC admins and they say it's an issue with QT5, which this system, soon to be decommissioned, does not support. What is the latest version of Ovito before QT5?
