Hi everyone

I'm going to build an equation based model which include periodic boundary conditions. I need to implement Bloch- Floquet Boundary Conditions in weak form.

Do you have any idea how to make it?

Thanks

Hello, have you figure this problem out? floquet boundary condition in weak form? I confront the same problem and really need your help

I used Dirichlet B.C. to apply floquet B.C. but not in a weak form.

Hello,
I am trying to apply the Bloch- Floquet Boundary Conditions by means of pointwise node in a 2D periodic structure. However, it seems that my method has something wrong. Could you help me to point out the incorrectness?

please upload your file here. I will take a look at it. I'm using 4.4.

Hello,
The size of my MPH file is about 25MB, which can't be attached. Could you tell me how to upload my file or could you give me your email?

Hello,

Did you solve the problem, I am facing the same problem. How can we apply a boundary condition in weak form. In fact I have my equation with "u" periodic function how can I apply this periodic function in comsol?

Thanks you.
