In principle, it's possible to run simulations on a non-uniform grid (see <a href="http://bug.medphys.ucl.ac.uk/papers/2013-Treeby-IEEETUFFC.pdf">this paper</a> for example). However, this isn't yet part of k-Wave.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/meshing-on-a-non-prismatic-domain#post-5859 Tue, 21 Mar 2017 02:40:39 +0000 gcordobaguerrero@gmail.com 5859@http://www.k-wave.org/forum/ <p>Dear all,<br /> I need to model a volcanic blast wave. This mean that the domain cannot be prismatic, as the bottom corresponds to ground coordinates.</p> <p>Is there any way to do that? Which is the best way? </p> <p>An easy task: lets hace an square (-1&lt;x&gt;1; -1&lt;y&lt;1) with just 3 ponits at each coordinate direction. I need something like: for x=0 make transform y=-1 to -0.5, y=0 to y=0.3 and y=1 to y=1. How to do that from makeGrid.m? Or even from a new script, lets say how the wave numbers become affected?</p> <p>Thanks </p>
