However, you could modify either <code>getPML</code> or the simulation functions (e.g., <code>kspaceFirstOrder3D</code> see line 617 onwards) to get different behaviour. </p> http://www.k-wave.org/forum/topic/how-to-set-pml-absorption-in-the-upper-left-and-right-directions#post-8944 Mon, 13 Nov 2023 02:23:29 +0000 Rmax 8944@http://www.k-wave.org/forum/ <p>How to set PML absorption in the upper, left, and right directions in 2D? Is the direction of PML only be left and right or up and down, Can I separate the top, bottom, left, and right settings separately？ </p>
