combine pressure acoustics with laminar flow and solid mechanics

Hello guys

I want to model a solid particle moving through a standing acoustic wave in a microchannel, but I don't know how to combine solid mechanics and pressure acoustics transient and lamnar flow. does anyone have any idea?

Thank you

If you are investigating motion in a standing wave, I do not understand why you want to use pressure acoustics transient. A possible way to approach the problem would be: use pressure acoustics frequency dependent to calculate the standing wave field, and use particle tracing in the laminar flow module with a force function depending on the standing wave field. I have addressed a related problem in publications in the proceedings of the 2018 and 2019 International Ultrasonics Symposium.
