Is your source mask defined at a single point?</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/time-varying-source-and-reflection-from-interface#post-6028 Thu, 29 Jun 2017 21:04:08 +0000 babakkh 6028@http://www.k-wave.org/forum/ <p>Hi,</p> <p>I am using k-wave for underwater acoustic simulation and my source is the acoustic pressure recorded from seismic-airgun. my source is 5 meters below the water surface. It seems I must use source.p-mode='dirichlet' since I know the values of the source term. But in this case the reflected acoustic pressure from water/air interface is very weak which is not correct. </p> <p>If I use source.p-mode='additive', then the reflected wave seems correct but this time the source is very different than the reality. </p> <p>Can you please help me to solve this problem? k-wave can't handle source and propagation from interfaces? </p> <p>Best regards,</p> <p>Babak </p>
