Select “Transient resonant analysis” on the Piezoelectric Analysis tab and perform the analysis.
See Piezoelectric Analysis tab for reference.
As a result, the displacement change over the time can be viewed.
Unless specified in the list below, the default conditions will be applied.

To see the time response, click [Results] -> [Display]. Select “Piezo/Time response” at [Solver], “Displacement” at [Field],
and “X component” at [Component] Then, click [Field Graph] at [Show Results] group and set the dialog box as follows.
Select “Horizontal axis: Mode (frequency, time, step, etc)”. See here for creating graph.
See [Field Graph] for more details.
