Hi All,
Thank you so much for taking the time to read this. I am currently encountering some issues with finding a solution for my simulation. For some background, I have a 2D simulation of an acoustically actuated microswimmer in a tank filled with water that generates 2nd order steady streaming. The microswimmer is actuated by a piezoelectric plate underneath at frequency f0 via Thermoviscous Acoustic-Structure Boundary, and the resulting acoustic velocity is found via Frequency Domain. Then these results are linked and used in a Stationary study for Laminar flow to obtain the 2nd order steady streaming caused by the oscillation of the microswimmer tail. Unfortunately, whenever at the resonant frequency of the system, the solution fails to converge. I am very curious on why this is so and would greatly appreciate any help. I have also attached my simulation. Thanks!
