That should be no problems as long as you set all the respective parameters appropriately (medium and grid). If you’re still stuck, post an example and we can take a look. It can also help to turn off the nonlinearity to start to help with debugging the problem. </p> http://www.k-wave.org/forum/topic/modelling-nonlinear-sound-propagation-in-air#post-8905 Wed, 06 Sep 2023 11:14:06 +0000 Ernst Uzhansky 8905@http://www.k-wave.org/forum/ <p>Hi everyone, </p> <p>Could you pleaswe give me an advice on how to calculate nonlinear sound propagation in air using k-wave 1D? k-wave is crashing if I use density and sound speed of air (1 kg/m3 and 343 m/s).</p> <p>After playing a bit with parameters, it seems to be working for density of water and sound speed of air (1000 kg/m3, 343 m/s) and even be working with a lower density (e.g., 100 kg/m3) but after that begins to crush. I know k-wave was not made for air-use but maybe you can give me a hint. </p> <p>Thanks,<br /> Ernst </p>
