Do you see something different?</p> <p>Best wishes<br /> Ben </p> http://www.k-wave.org/forum/topic/source-terms#post-8169 Mon, 07 Jun 2021 10:07:59 +0000 akuliesh 8169@http://www.k-wave.org/forum/ <p>Dear all,</p> <p>I am working with point sources and was wondering what is the logic behind them. My source is omnidirectional, so I use source.p to define the emitted pressure. But how kWave interprets the r0, distance from the source at which the input pressure was estimated? Is it the grid size? </p> <p>In my derivations the propagating spherical wave follows the equation p(r) = p(r0 )r0/r exp(iwt-ikr). </p> <p>Thank you,<br /> Alina </p>
