Periodic Condition
The Periodic Condition allows modeling just one unit cell of a periodic structure, such as superlattices.
Periodicity Settings
Select an option from the Type of periodicity drop down menu: Continuity (the default) or Floquet-Bloch periodicity.
•
For Floquet-Bloch periodicity, enter the k-vector for Floquet periodicity kF (rad/m). The default is the null vector, reducing the condition to be equivalent to Continuity. For time dependent studies, the Floquet-Bloch periodicity option does not apply. If erroneously selected, it will be reduced to the continuity condition.
Destination Selection (subnode)
If desired, use this subnode to manually select the destination boundary for the periodic condition.
