Hi, I have a model; I want to simulate a focused ultrasound transducer In water and the pressure it generates at its focal point. Is this the correct way to do it? It is done using coupled-Field harmonic, the curved part is the PZT, and the region at front and back is acoustic -Water, and there is a structural body within the water made up of steel which I want to deform. What should be the Boundary condition for this curved Transducer? I have constrained it from all faced except front and back where voltage is applied.
