Create a Translational Periodic Boundary Condition

  1. Choose Home tab→Loads and Conditions group→Periodic Boundary Condition .

  2. In the Periodic Boundary Condition dialog box, select Translational Periodicity from the Type list.

  3. Define the Master Region by selecting one of the polygon faces of the periodic boundaries.

  4. Define the Slave Region by selecting the matching faces on the other periodic boundary.

  5. (Optional) You can also exclude one or more polygon faces from the periodicity by clicking Select Object in the Master Region or Slave Region groups, and then selecting the polygon face(s) to exclude.

  6. (Optional) Select the pressure drop From Master to Slave by specifying the Pressure.
