You can use <a href="http://www.k-wave.org/documentation/example_ivp_opposing_corners_sensor_mask.php">opposing corners</a> if you want a short-hand for a sensor covering the whole grid. You can also use the <code>sensor.record_start_index</code> if you don't need the whole time series.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/time-dependent-pressure-on-full-grid#post-8065 Fri, 19 Feb 2021 01:10:54 +0000 scottzig 8065@http://www.k-wave.org/forum/ <p>Hey there,</p> <p>I'm trying to calculate the derivative of an error function, and as a part of this I need to calculate the solution to the adjoint equation. I would like to move into the frequency domain after solving the adjoint equation and in order to do this I need to take a Fourier transform over the time dependent pressure wave on the entire grid. That is, I need a time dependent pressure wave on each grid point. An obvious way to do this is to place a sensor on each grid point and have it record the pressure. However, I'm curious if there is a slicker way to accomplish this in k-Wave. Thanks in advance for your help.</p> <p>-Scott </p>
