Hi all,
I hope everyone is doing well and is in good health.
I want to simulate a Honeycomb Core Geometry Sandwich Panel Metamaterial with COMSOL Multiphysics for sound transmission study. It is needed to use beam elements of quadratic geometry order to create the geometry of unit cell. In 2D I do not know how to do that! Do you have any idea about it?
I appreciate your time and consideration.

Hi
In my opinion, you should use the visualization of a periodic structure from a unit cell (Honeycomb). For this method, you can look at the model mentioned below:
