There are two related reasons: boundary conditions cannot be applied directly, but must be set by changing the material properties. If there is a large change in material properties, as you will need here, then you may need many points per wavelength to model it accurately. In which case you may as well use a finite element model in which the boundary conditions can be explicitly included. The other advantage of k-Wave is for large-scale problems, when the domain is many hundreds of times larger than a wavelength, which I doubt is the case here.</p> <p>Hope that helps,</p> <p>Ben </p> http://www.k-wave.org/forum/topic/circular-hollow-waveguide#post-3833 Tue, 30 Jul 2013 10:07:59 +0000 benito 3833@http://www.k-wave.org/forum/ <p>Hi,<br /> can I use k-wave for study the propagation of ultrasonic wave in an hypodermic needle? I need to determine the radiation diagram at the exit of the tip<br /> Thank you </p>
