shear wave propagation simulation

Hi,

I am trying to simulate a shear wave propagation in a homogeneous, isotropic, and linearly elastic material. I constructed a cube for simulation and applied fixed boundary condition to one side of the cube. The displacement was prescribed to the other side of the cube. The purpose is to get four sampling points in one vibration cycle. So I used "Frequency Domain" for my study. However, when I export the results to matlab, I could not see the temporal changes in one vibration cycle. Could anyone help me on this?

Also, does anyone know how can I view the displacement plot in comsol? I only see the von Mises stress in the result tab. But I could view the displacement in the results exported to matlab.

Thank you!
