Online Tutorial: Piezoacoustic Optimization
Fanny Littmarck | December 17, 2012
Tomorrow, December 18th, we are holding an online tutorial on piezoacoustic optimization. The tutorial will run for about half an hour starting at 12:30pm Pacific Standard Time (PST). If you are already familiar with the piezoacoustic transducer model in the model library, you should tune in for this further-developed version of the model.

Piezoacoustic Optimization, Multiphysics
COMSOL has long been used to simulate piezoacoustic applications. The fact that you have to couple the already tightly-coupled electrostatics and structural mechanics within the piezo physics to the acoustics field makes it a great example of multiphysics application. We have previously blogged about such applications, and we have a few models in the Model Gallery that show how to set up these types of models (check out the radially polarized spherical piezoelectric acoustic transducer and the piezoacoustic transducer models). One of the keynote speakers at the COMSOL Conference in Milan also talked about the subject, in his presentation on piezoelectric transducers and ultrasound imaging.
The online tutorial will cover an introduction to COMSOL and the piezoacoustic transducer model, followed by a live model set-up. My colleague, John Dunec, has extended upon previous models by simulating a piezoacoustics transducer in the real setting of a loudspeaker. He will also show you how the Optimization Module can be used to find the ideal depth for the appropriate frequency.
