How can I fix periodic boundary during animation
« on: January 16, 2019, 04:30:52 PM »
I have a xyz format file and try to visualize it.

Problem is, periodic boundary is changing through the animation. It seems that OVITO choose the min/max coordinate as a cell size when I use XYZ file.

How can I fix the periodic boundary position during animation?

Hi,

in order to avoid this I would recommend to use the extended xyz file format, where the actual cell is defined in the header, see e.g.
http://libatoms.github.io/QUIP/io.html#extendedxyz
for more details.

If your simulation cell does not change during the course of your simulation there is a quick workaround: You could define the cell vectors yourself by adding the Affine Transformation modifier to your pipeline - use the options "Transform to target box" and "Operate on" Simulation cell only.
