After you have chosen <code>dt</code> (see the k-Wave manual if you need further details), then <code>Nt * dt</code> will define how long the waves propagate for. For example, if you have a domain of a certain size and sound speed, you can set <code>Nt</code> such that the waves have time to propagate across the domain for example.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/nt-one-of-the-parameters-of-kgrid#post-7285 Sun, 08 Mar 2020 08:08:28 +0000 kian_esmailian 7285@http://www.k-wave.org/forum/ <p>Dear Bradley<br /> I can't understand the mathematical formula of calculating kgrid.Nt, i know it related to Nx and Ny but i don't understand how can we calculate it.<br /> Beside these parameters, is this related to PMLSize?<br /> Best regards<br /> Kian </p>
