A distributed source can be considered as the sum of individual point sources, so the same should hold if the source is a bowl.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/source-sensor-interchange-are-the-two-cases-corresponding#post-8021 Sat, 23 Jan 2021 16:31:19 +0000 lishine 8021@http://www.k-wave.org/forum/ <p>Case 1:<br /> 1) Set souce.p0(...)=1 (set to single point)<br /> 2) Set sensor.mask=Makebowl(...)<br /> 3) Sum all sensor data<br /> Case 2:<br /> 1) Set souce.p0(...)=Makebowl(...)<br /> 2) Set sensor.mask=1</p> <p>Are the simulation results (waveform) consistent?(Ignoring amplitude)</p> <p>Note: This problem can also be explained as whether the sensor and source are reversible during simulation </p>
