Dear Daniel,
Thank you very much! I can test my period boundary condition added truly.
Your advision helps me a lot !
As my question is about periodic boundary condition like

just like Dirichlet boundary condition.
But if "periodic boundary condition" means that all

Thanks you for clarifying this.
Can you try
