## Problems about Periodic Conditions in the tutorial model “Periodic Boundary Condition”

Posted Feb 10, 2013, 3:10 PM EST RF & Microwave Engineering 8 Replies

Hi all,

Recently I confront one confusion about periodic conditions in the tutorial model - Periodic Boundary Condition. In Periodic Condition, it selects only boundaries 1 and 6 which are parallel with the yz-plane. As you know in the model, the cube should be a repeated cell and certainly repeated on the xy-plane both in the x direction and in the y direction. However, boundaries 1 and 6 only correspond to x direction. So what about repetition in the y direction?

Then I try to select both boundary 1, 6 parallel with yz-plane and boundary 2, 5 parallel with xz-plane in the Periodic Condition. But some problem occurs just as follows:

Errors during multiphysics.

Failed to find destination boundaries or destination selection empty

- Feature: Periodic Condition 1 (pc1)

I don't know why this happens and how to set Periodic Condition that means a repeated cell in the xy-plane both in the x direction and in the y direction.

Thank you so much.
