This causes the point source to not reflect waves. Additive sources are the default source type for the source structure but you can change it by setting source.p_mode to 'dirichlet', which just means that the point source will now act as a reflector. </p> http://www.k-wave.org/forum/topic/reflection-from-the-source-surface#post-7373 Mon, 06 Apr 2020 17:11:37 +0000 apanfilova 7373@http://www.k-wave.org/forum/ <p>Hi Bradley, what is a normal additive source? is source.p of a circular transducer in 2D normal additive? </p> http://www.k-wave.org/forum/topic/reflection-from-the-source-surface#post-7342 Wed, 01 Apr 2020 14:56:17 +0000 Bradley Treeby 7342@http://www.k-wave.org/forum/ <p>Hi Anastasiia,</p> <p>Wave propagation is modelled in all directions (not just forwarded propagation). However, if you use a normal additive source, then the source pressure is added to the existing field. This means there will be no reflection from the source surface. </p> <p>Brad. </p> http://www.k-wave.org/forum/topic/reflection-from-the-source-surface#post-7327 Thu, 26 Mar 2020 15:20:49 +0000 Anastasiia 7327@http://www.k-wave.org/forum/ <p>Hi Bradley Treeby,<br /> I was wondering if k-wave also simulates reflection from the source. For example, if i am simulating a slice of a medium in water (3D simulation), the wave that is reflected from the water-medium interface, is it also reflected back by the source or is only forward propagation modelled?<br /> Thank you! </p>
