Replicate — OVITO User Manual 3.6.0 documentation

# Replicate

This modifier copies all particles, bonds and other data elements multiple times to visualize periodic images of a system.

The Operate on list in the lower panel lets you select the types of data elements that should be replicated by the modifier. By default, the modifier extends the simulation cell appropriately to encompass all generated images of the system. If not desired, you can turn off the option Adjust simulation box size to keep the original simulation cell geometry. You should be aware, however, that this produces an inconsistent state, where the periodicity length no longer fits to the explicitly replicated contents of the simulation cell.

## Parameters

Number of images - X/Y/Z

  These values control how many times the system is copied along each simulation cell vector.

Adjust simulation box size

  Extends the simulation cell to match the size of the replicated system.

Assign unique IDs

  This option lets the modifier assign new unique IDs to the copied particles or bonds. Otherwise the duplicated elements will have the same identifiers as the originals, which may cause problems with other modifiers (e.g. the Manual selection modifier), which rely on the uniqueness of identifiers.

  For replicated particles, this option also adjusts their `Molecule Identifier` property if it exists.
