The Periodic submenu is used to specify how a periodic connector or domain should be created.
Once created, the periodic connector (or domain) and the original counterpart become slaved periodically. That is, any future changes to one of them (i.e.,
transformation, redimension, redistribution, etc.) will be reflected in its twin. The only exception to this is the display attributes of a periodic pair can
Note that the Periodic command is only available when the original selection does not have a periodic twin. This is because the periodicity is
enforced in pairs: no more than two connectors or two domains may be periodic with each other.
The periodicity information is available in the List panel through entity names. As shown in the figure below, in parentheses next to each periodic connector
there is a periodic tag and a name indicating its twin. If either of these two connectors is deleted (or joined), the periodicity will be broken immediately and
the other will remain in place.
Periodicity is reflected in the names of a slaved pair in the List panel.
To facilitate the selection of periodic entities in a grid system, check the Periodic check box in
the Mask panel. This creates a pick mask such that only periodic entities may be selected.
Check the Periodic check box in the Mask panel to allow only periodic entities to be selected.
Note that the Periodic command does not automatically assign a periodic boundary condition to a periodic pair of domains (3D) or connectors
(2D). If supported by your current CAE solver, periodic boundary conditions must be set via the CAE, Set Boundary
