If you want to set sound-hard or sound-soft boundary conditions at the edges of the domain, you could try the suggestions from <a href="http://www.k-wave.org/forum/topic/room-enclouse-acoustic-simulation">this post</a>.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/pat-2-d-imaging-using-a-hard-or-a-soft-boundary#post-3797 Sat, 20 Jul 2013 01:47:12 +0000 koknit 3797@http://www.k-wave.org/forum/ <p>Sir, I am new to k-wave. I have been reading through a paper by Dr.Lihong V.Wang and X. Yang on Boundary conditions in PAT and Image reconstruction. (2007) I was curious to test the results out and would like to know if we could do something add a boundary for the image and just take the pressure measurements as shown. </p> <p>Thank you. </p>
