Im running the example codes and in the Ultrasound Beam patterns example, the focus distance is set in the code to be 20e-3, however when the simulation runs, i notice that in the resulting beam pressure map, the highest maximum amplitude (dark red region) is to be found at around 10e-3 on the y-axis. My question is, isnt the highest beam pressure supposed to be found at the focus distance that we set?
Thank you
