您好!
感谢您的评论。

二维/三维声子晶体的Floquet条件设置需要根据晶格形式设置扫描路径,建议您先根据您的声子晶体的晶格形式写出其对应的不可约布里渊区,再依次扫描。晶格形式及不可约布里渊区的相关概念建议查阅相关的书籍或论文学习。

如果有进一步问题,建议您联系COMSOL的技术支持团队:

谢谢!

Hi!
The wave number k varies from 0 to pi/Li (Li is the length of your periodic unit cell). Then define the direction of k that we’re going to sweep. The direction depends on irreducible Brillouin zone, where the direction between any two vertices should be swept.

Thank you very much for your sharing!
I have some questions that have been bothering me for a long time.

Firstly, I have been working on Band Gap calculation recently, and I am confused how to make my calculation for Shear Horizontal Mode (SH wave) because I can’t find anywhere that I can set to tell COMSOL to make it for SH wave or SV wave or Lamb wave.

Secondly, I find that PML has no effect on absorbing wave when it is used to simulate transient wave motion by using solid mechanics module.

Can you give me some advice?Thanks a lot!
