Issue:

This error, "Failed to apply periodic boundary conditions. Please check the Design volume." came up when I was running the Homogenize Unit Cell block.

Applies to:

• Simulation
• Homogenize Unit Cell

Cause:

This error is occurring because there is an issue with the Design Volume input.

Solution:

To avoid this issue, use the Bounding Box of the mesh being homogenized as the Design volume. This ensures there are no boundary condition errors.
