Jan Stránský proposed the following answer:
It depends on definition.
In Yade, if you enable periodicity, it is applied in 3 direction, no matter what.
But enlarging the periodic cell dimensions, you can "disable" some directions, making the simulation being practically periodic only in some direction(s).
Still, the **visualization** is done such that all particles are displayed inside the cell. But the periodicity itself (i.e. periodic contact detection between particles and periodic images of other particles) is not effectively present in "disabled" directions.

Cheers
Jan
