There's not automatic way I'm afraid. </p> http://www.k-wave.org/forum/topic/placing-source-at-edge-of-kgrid#post-8451 Thu, 03 Feb 2022 19:23:26 +0000 zachd495 8451@http://www.k-wave.org/forum/ <p>Hi Bradley,</p> <p>Thank you for the help! I apologize if I was not clear. </p> <p>I have a cylindrical volume that when imported into k-Wave, it is automatically placed at the center of the kGrid. I would like to move the source so that one end of the cylinder is at the edge of the computational grid. </p> <p>Thank you very much! </p> http://www.k-wave.org/forum/topic/placing-source-at-edge-of-kgrid#post-8450 Thu, 03 Feb 2022 18:07:01 +0000 Bradley Treeby 8450@http://www.k-wave.org/forum/ <p>Not sure I follow exactly - the position of the source is defined by the source mask, so you can make sure that this is against the edge of the grid (be careful to set <code>&#39;PMLInside&#39;, false</code> if you're doing this though). </p> http://www.k-wave.org/forum/topic/placing-source-at-edge-of-kgrid#post-8449 Wed, 02 Feb 2022 20:27:18 +0000 zachd495 8449@http://www.k-wave.org/forum/ <p>Hi all!</p> <p>Sorry if this is a simple question, but is there a way to move user-inputted source (a 3D array) so that the start of the source is at the edge of the computational grid? </p> <p>Thank you very much! </p>
