In my research work at the Department of Acoustics, I have been using k-Wave for about six months now to numerically model sound propagation in a coastal wedge. There are a few nuances I would like to clarify, as they are preventing me from fully converging my results with the analytical solution.</p> <p>Here’s the issue: I am currently trying to numerically solve the problem of sound propagation in an ideal fluid wedge with acoustically soft boundaries using k-Wave. The analytical solution for this scenario is presented in the paper by Buckingham and Tolstoy (1990). In k-Wave, I’ve encountered a problem where I cannot set boundary conditions on the wedge edges—specifically, the requirement that the acoustic pressure must be zero at the boundaries. Most likely, this is the reason I am unable to achieve full convergence with the analytical solution. Therefore, I would like to know if it is possible to set such boundary conditions in k-Wave, or whether k-Wave automatically accounts for these boundary conditions based on the defined medium model.</p> <p>Thank you to anyone who responds and helps me resolve this issue!</p> <p>Best regards,<br /> Artyom </p>
