Thank you for your answer.</p> <p>Best regards,<br /> Andrea </p> http://www.k-wave.org/forum/topic/steering-a-linear-array-in-pstdelastic2d#post-7999 Tue, 19 Jan 2021 19:33:12 +0000 Bradley Treeby 7999@http://www.k-wave.org/forum/ <p>Hi Andrea,</p> <p>If you are in a fluid region in an otherwise elastic domain, the acoustic pressure is equal to the negative of the normal components of the stress. So in short, you can use <code>source.sxx</code> etc and set to <code>-source.p</code>. Have a look at the <a href="http://www.k-wave.org/documentation/example_ewp_shear_wave_snells_law.php">Shear Waves And Critical Angle Reflection Example</a>.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/steering-a-linear-array-in-pstdelastic2d#post-7992 Tue, 29 Dec 2020 19:39:53 +0000 Andrea Addison 7992@http://www.k-wave.org/forum/ <p>Hi All,</p> <p>I have two questions about source design in pstdElastic2D. </p> <p>1-Can we apply the linear array example* source into pstdElastic2D? I couldn't find the "source.p" in the pstdElastic2D's source list. I was wondering if we have a flexibility to design a source in which different grids of the source transmit arbitrary input signals.</p> <p>2-We are not allowed to use "source.p" command in the pstdElastic2D. How we can generate a monopole pressure source in the elastic simulation? </p> <p>*http://www.k-wave.org/documentation/example_tvsp_steering_linear_array.php</p> <p>Andrea </p>
