I'd recommend at least 3 points per wavelength for a homogeneous simulation. This would correspond to a dx of ~ 0.1 mm, where:</p> <p><code>dx = c0 / (PPW * f0)</code></p> <p>More details in Sec. 3.2 of the k-Wave user manual.</p> <p>Brad </p> http://www.k-wave.org/forum/topic/acoustic-radiation-force-simulation#post-6854 Mon, 20 May 2019 20:43:43 +0000 lokesh 6854@http://www.k-wave.org/forum/ <p>Hi,<br /> I simulated a pressure distribution using k-wave toolbox with the following parameters (N_active = 64, focus = 20mm, f0 = 5MHz, burst length = 200μs, density = 1000 kg/m^3, speed of sound = 1540m/s, dx=dy=dz = 0.16mm). The link is added at the end to visualize the image.<br /> The image does not look as expected for the focused transducer. I am new to K-wave simulation toolbox. Please provide suggestions where I am going wrong.<br /> Thank you in advance.</p> <p><a href="https://ibb.co/fpwK11D" rel="nofollow">https://ibb.co/fpwK11D</a> </p>
