I am working on an acoustofluidic simulation using ANSYS Fluent (Workbench). In my simulation, I have a cuboid, and I want to apply harmonic oscillations to its bottom surface. The goal is for these oscillations to induce motion in the incoming fluid.

I’ve tried many approaches—using dynamic meshes, UDFs, and more—but I haven’t been able to get the wall to oscillate. As a result, I don’t see any noticeable change in the fluid flow.

How can I achieve this? Could you provide a detailed guide or structure on how to set up such a simulation? Any helpful resources, such as YouTube tutorials or documentation, would also be appreciated.
