From the Calculate menu,
select Calculate.
During the computation,
use the Calculate Window, as well as View Process Info commands
in order to monitor the progression of the computation. The amount of information
printed in the Calculate Window is controlled by the Printing setting
(Problem Data section).
When the computation is finished, GiD displays the following message.

Admittance/Impedance
Result
Note that the admittance
is given without correction for the model symmetry.
The magnitude of the admittance
should be multiplied by 2π. This is easily
done by using the comma separated value (CSV) files
located in the working directory. Use Open Shell from
the ATILA menu to access the working directory.
Note that wather load shift the transducer resonance
frequency lower and provides significant damping.

Note that we have superposed the magnitude of
the Von Mises Stress on the Real Part of the structure
deformation.
Note that you may want to change the deformation
factor (here it is set to 2·107).
Note that the number of frames in the animation
is set in the Preferences (ATILA menu).
Pressure Observation
You may also want to display the deformation and
the pressure Underwater at the frequency of maximum
admittance (32.25kHz).
The solid
part of the transducers appears disconnected
from the water domain. This is normal, since there
are no displacements associated with the fluid
elements used in this computation. Similarly, the
solid part is not colored, since we are plotting
pressures, and that there is no pres-sure degree-of-freedom
in the elastic and piezoelectric domains.
Transmitted Voltage Response (TVR)
Lastly, we can use the acoustic postprocessing
features available. For instance, display the
Transmitted
Voltage Response (TVR).
