There are a few posts about having different time series inputs for different source points. In short, yes you can do it, but you have to make sure you stack the source time series in the right order so they match with the right points.</p> <p>Best wishes<br /> Ben </p> http://www.k-wave.org/forum/topic/to-define-different-phase-and-amplitude-for-each-source-in-multi-source-medium#post-8697 Thu, 26 Jan 2023 04:57:42 +0000 hamids 8697@http://www.k-wave.org/forum/ <p>I defined a medium with several elastic wave sources according to the following codes. In this simulation, all sources have the same phase and amplitude. Now, I need to define different phases and amplitudes for each source. For instance, source #1 has a phase equal to 0 and an amplitude equal to 1, source #2 has a phase equal to 90 and an amplitude equal to 2, and so on. Is there any way to do so?</p> <p>source_y_pos=[ceil(Ny/8), ceil(Ny/4), ceil(3*Ny/8), ceil(Nz/2), ceil(5*Ny/8), ceil(3*Ny/4), ceil(7*Ny/8)];<br /> source.u_mask (source_y_pos, source_y_pos, 1)= 1;<br /> source.u_mask (source_y_pos, 1, source_y_pos)= 1;<br /> source.u_mask (1, source_y_pos, source_y_pos)= 1;<br /> source.u_mask (source_y_pos, source_y_pos, end)= 1;<br /> source.u_mask (source_y_pos, end, source_y_pos)= 1;<br /> source.u_mask (end, source_y_pos, source_y_pos)= 1;<br /> source_freq = 500;<br /> source_mag = 50;</p> <p>source.uz = source_mag*sin(2*pi*source_freq*kgrid.t_array); </p>
