Hello:
We used 2D module to simulate the surface acoustic wave device (similar to the model surface acoustic wave gas sensor) .
This means that this model has nothing to do with the third direction .
Because the material direction problems , so we use Y128X-LiNbO3 material to simulate now.
Let it has a displacement of energy in three directions .
So we need to solve the problem by 3D models, but I do not know how to set boundary conditions .
Can you please teach me how to set the boundary conditions?
Thank you very much.

Hi Tai Xiang Wang,
Are you from China?I come from China,and you? Recently, I use COMSOL to simulate the surface acoustic wave device, too.Will be glad to make a friend with you, to communicate with each other about the simulation of SAW device.
Look forward to your reply!
Best regards!
