" </p> <p>A naive approach is to assign the temporal signal by setting</p> <p>source.p = pressure signals;<br /> source.p_mode = 'dirichlet';</p> <p>Is there any relevant examples to explain how to do this?</p> <p>Thanks </p> http://www.k-wave.org/forum/topic/impose-dirichlet-pressure-booundary-conditions-in-kspacefirstorder3d#post-9182 Wed, 12 Feb 2025 21:05:37 +0000 HD Y 9182@http://www.k-wave.org/forum/ <p>Hi, is it possible to impose Dirichlet boundary conditions in kspaceFirstOrder3D? Thanks a lot. </p>
