I've done with the "Heating By A Focused Ultrasound Transducer" script and by using the "example_at_focused_bowl_3D" script. I am using the same parameters for the transducer and for the medium in both examples, however, the peak pressure at focus is of 0.5 MPa in the former and of 2.5 MPa when running the later. Does anybody had encounter with this issue before? What could be happening?<br /> Thanks! </p>
