Hi. May I ask if OVITO software can visualize the dislocation lines and their adjacent atoms? I mean the atoms used to determine the dislocation lines.

Hi,

It depends on how you mean it. Ovito can display atoms and dislocation lines simultaneously. The DXA modifier, which generates the dislocation lines, assigns a structure type to every atom. This information allows you to select the perfect crystal atoms and remove them from the view. What remains are the atoms that belong to crystal defects (any kinds of defect, not just dislocations).

However, the DXA algorithm doesn't tie defect atoms to specific dislocation lines. If this is what you are asking for, then the answer would be "no".

Best regards,
Alex
