The approximations made regarding the nonlinear term are equivalent ie, it accounts for the cumulative nonlinearity but not local nonlinearities.</p> <p>Hope that helps.</p> <p>Best wishes<br /> Ben </p> http://www.k-wave.org/forum/topic/what-are-the-nonlinear-terms-simulated-in-k-wave#post-8691 Sat, 07 Jan 2023 15:31:28 +0000 KailingYI 8691@http://www.k-wave.org/forum/ <p>Hi,</p> <p>My acoustic issue is non-linear, so I am wondering what are the non-linear terms simulated in K-Wave?</p> <p>According to the K-Wave user manual, it seems to solve the 1st order partial differential equation equivalent to the Westervelt equation? If not, how does it differ from the Westervelt equation? </p>
