How to use this code for topology optimization of tubes?

[solerzhuxy]

Hello, Dr. Lu,
I am new to the hPINN code. Now I am encountering a task of topology optimization for tubes with periodic hollowed patterns under mechanical loading (bending, compression, etc.). The patterns are periodic along the circular direction. But furthermore, I wish to realize more complicated topologic structure, such as periodic structure along the axis direction. The optimization object is the minimum of total strain energy under multiple loading conditions, e.g., bending and compression.
So in my case, how can I solve this issue by hPINN? Could you give me a detailed road path to follow?
Thank you!
