How add standing SAW displacement and impedance condition

Please login with a confirmed email address before reporting spam

Hi everyone

I have a model that simulates acoustic pressure and velocity in a microchannel. But I don't know how to add boundary conditions. Two formula: 1. Impedance condition 2. Standing SAW displacement Do anyone can tell me how can I set it up? I upload my .mph

My reference : https://doi.org/10.1039/C5LC00231A https://www.comsol.com/paper/simulation-of-saw-driven-microparticle-acoustophoresis-using-comsol-multiphysics-25552

The case have to use three interfaces Thermoviscous Acoustics, Creeping Flow and Particl tracing for Fluid Flow
