Modeling intensity field from high-intensity ultrasound source WITHOUT acoustics module

Hi,

I cannot afford to buy the Acoustics module, so I'm wondering if it's possible to model the energy being deposited into a material due to multiple ultrasound sources. The KZK equation can be used to calculate the intensity as a function of radial and axial distance from a source. Anyone have experience with this? Is there a situation where I can use the equation-based modeling? Thanks.

Hi

everything is possible, as the acoustic module is built upon the basic COMSOL module. But if the price is in the upper module section it probably also means that it's quite some work ;)
By the way I'm also fighting to get an investment to pay me that module, not really for the acoustic sound part, more for all the structure fluid interactions and damping of the structure. In the basic COMSOL you have one entry and an example that deals with acoustic, but it goes not that far. Perhaps you should consider the model builder to make your own module

Good luck

Thank you Ivar. I'll take a look at the module builder. I haven't even taken a look at it, so I'm sure it will be a lot of work. You'll probably hear from me again soon!
