The default plot range is [-1, 1]. You can set <code>&#39;PlotScale&#39;, &#39;auto&#39;</code> if you want to double check. The second is whether the frequency is still supported by the computational grid (the maximum frequency is reported on the command line output).</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/increasing-the-amplitude-of-source-makes-wave-propagation-video-wrong#post-6753 Mon, 11 Feb 2019 20:57:31 +0000 Zheng 6753@http://www.k-wave.org/forum/ <p>Sorry, this problem appears with both higher amplitude and frequency. </p> http://www.k-wave.org/forum/topic/increasing-the-amplitude-of-source-makes-wave-propagation-video-wrong#post-6751 Sun, 10 Feb 2019 21:29:53 +0000 Zheng 6751@http://www.k-wave.org/forum/ <p>Hi,</p> <p>I defined a point source in water. The sound wave propagation looked good at relatively low frequencies. But once I gave it a higher frequency, the wave propagated with a cross shape and the color was black and grey. </p> <p>Can anyone explain this to me?<br /> Is there any value limits of frequency or amplitude?</p> <p>Thanks in advance! </p>
