However, we are currently working on a nonlinear version which should be out around mid-year.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/non-linear-wave-propagation#post-143 Wed, 11 May 2011 14:03:06 +0000 Steffen 143@http://www.k-wave.org/forum/ <p>Hi,<br /> is it possible using k-wave to simulate a high power focused ultrasound transducer? I mean in the focal region the local pressure amplitude will be high let's say 10^6 Pa so non linear effects are expected because the pressure is much higher than the atmospheric or surrounding DC pressure and absolute negative pressure is not expected. </p>
