In my comsol simulation, I am trying to form an ultrasonic standing wave field, hence the study that I am using is the frequency domain study. The resonant frequency of PZT-8 is 960 kHz. While running the simulation, I got a really small pressure acoustic wave field. This might be due to a number of reasons:
1. Wrong or missing boundary conditions
2. The material that I am using for the transmission layer between the transducer and the fluid domain
3. There is no coupling between the piezoelectric effect + structure mechanics (solid) with the fluid domain.

Please have a look at my simulation and the brief report. Please tell me whats wrong with it.
P.S. I am using a Classkit License Comsol Multiphysics V5.2, hence I have given the brief report for you to check if you cannot use the Comsol version that I am currently using.
Hi,
I can't help you with the question, but have you tried asking it to the Comsol support guys? It's free and I've had real good experience with them. Usually they get back to you within a day.

Thanks Ivaylo, my license is classkit, hence they couldn't give any support. Unless my license is for research purposes then they would help me. I am doing this for my thesis B. Do you think it is actually possible to look at the movement of particles from a time range of (0,0.1,20) to look at how a 2.5MHz ultrasonic standing wave field concentrate the particle within its bands?
I was told in order to find the movement, it would take at least a time step of 1/2.5MHz within the 20s time range. I think this would take more than a few weeks to give me the results.
I am looking forward to create a simple comsol module for ultrasonic piezoelectric transducer over a water and find the pressure profile of it, any help??
