The time interval used is printed to the command line. You can easily define this yourself by setting <code>kgrid.t_array</code> before running the simulation. There are some examples of how to do this at the end of section 3.2 in the k-Wave manual.</p> <p>Hope that helps,</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/sampling-frequency-1#post-5214 Fri, 21 Aug 2015 20:35:50 +0000 stang 5214@http://www.k-wave.org/forum/ <p>I made a grid of 6.4mm*6.4mm (Nx=64,dx=0.1e-3). After I ran the simulation, I got the pressure from the sensor_data, and it contained 370 point. My question is, what is the time interval between points of sensor_data? what is the total time of the 370 points?</p> <p>I checked kgrid.dt, it is 'auto'.</p> <p>Thank you. </p>
