Which parameter do you want to record? It's possible to split the particle velocity into compressional and shear components.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/generating-p-and-s-waves-separately#post-6887 Wed, 19 Jun 2019 14:40:44 +0000 Alex91 6887@http://www.k-wave.org/forum/ <p>In the MATLAB version of K-wave, I would like to be able to simulate and detect the pressure field generated by an initial pressure distribution within a three-dimensional heterogeneous propagation medium, but I would like to separate the compressional (P) from the shear (S) wave.</p> <p>I tried to do that by setting:</p> <p><code>medium.sound_speed_shear = 0; (P wave)</code></p> <p>or</p> <p><code>medium.sound_speed_compression = 0; (S wave)</code> </p> <p>respectively. I wanted to ask if this makes sense from a physical perspective. In terms of results I think I am getting decent P waves, but the S waves are simply arrays full of zeros. </p>
