Hi,

Does anyone know how to carry out ultrasonic ndt simulation in solids or other structures using comsol? I want to carry out beam propagation using an array of transducers in a solid using comsol. Any help regarding this would be welcome!

Thanks!

Hello Chirag,

I think your question might be too general. At first, you need to investigate the "physics" you are working on. It seems that you work in "Acoustics", once again, make sure that you pick the right one because there are several "physics" inside "Acoustics Module". You should take a look at the manual of this module and several examples on the library. For an array of loudspeakers, you might look at the example "Bessel Panel".

The Bessel Panel describes how to use "Points" to model an array . You might plot a circle or any shapes and define them with "Incident Pressure Field" to mimic a source.

Best,

Quoc

Hi Quoc,

Thank you for your reply. What i am trying to do is model the beam field from a pizeoelectric transducer into a solid, when the transducer is in contact with the solid or when there is water between the pzt and solid. The frequency is in terms of MHz. So the physics underlying would be acoustic in terms of fluid case and then structural interaction
