2. Does the Solution->Probe->Position means that I could get the displacement response of the IC chip? Since I thought that the directional deformation might not be a good representation of the experiment while the displacement response should be a better choice. If Probe could help me to see what happened for the displacement response. I do meet a problem that shows as following, It seems that I failed to pick the geometry.
3. I would like to know how did you check the frequency by using the spectrogram within the MATLAB? Is that possible that I could take a look at your code, I might use the wrong command.
