So one way to speed up the simulations would be to increase the time step (or CFL). For initial value problems you could also use the function <code>kspaceSecondOrder</code> which is faster than the equivalent first order functions. Alternatively you could use other numerical approaches such as that used in <a href="http://www.egr.msu.edu/~fultras-web/">focus</a>, which will be much faster.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/using-k-wave-for-linear-homogeneous-cases#post-5271 Fri, 09 Oct 2015 16:15:13 +0000 kaius 5271@http://www.k-wave.org/forum/ <p>Sometimes it is convenient to run a faster simulation with linear and homogeneous conditions with the same array that one might use later with the added complexities. What's the best way to do this? One could, of course, use Field II but that introduces other concerns. </p>
