The 2D axisymmetric geometry used for COMSOL simulation in this study. The LIPUS piston transducer is defined as a flat line, while the water, dialysis membrane, nylon clip, and acrylic holder domains are labelled for reference. The bottom of the dialysis chamber setup is an acoustic absorber and defined as a PML. PMLs are also set on the outside of the dialysis chamber walls, as no significant reflection from outside the chamber is considered.
