How to couple acoustic domain with structural mechanics domain when a moving load is given

Please login with a confirmed email address before reporting spam

Hi friends
I am doing a moving loading simulation in comsol. What I wanna simulate is a moving load like a tire pass on the ground surface. I learned the trick from an example called Peristaltic Pump which used a gaussian distribution in both time and space domains to control a moving load to a boundary.
Yeah, I did archieve this. However, when I look into the acoustic domain, it seems the coupling failed. Nothing was there. I set the boundary between the air and solid interface as structral acceleration and it showed no error as hint.
But the results tell me the acoustic domain had nothing coupling with the solid vibration.

So, any suggestion or similar experiences


Thanks a lot

I have been encountering the similar problem, while i couldn't handle it.meanwhile,i'd like to ask a question: which mode do you choose to solve for,p or uvp ? and the difference between the two modes. if you are convenient , connect me via the QQ 280040899 or fhyd212@163.com
