Other tests will depend on context (e.g., comparison to an analytical solution, other numerical tool, or maybe an experiment).</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/assessing-the-error-in-the-simulation#post-8298 Mon, 16 Aug 2021 17:06:14 +0000 Anastasiia 8298@http://www.k-wave.org/forum/ <p>Hi Bradley,<br /> I have run a simulation in an attenuating, heterogeneous, nonlinear medium, where i recorded the propagating pressure field emitted by a circular pressure source. I would like to assess how accurate it is. As i understood from he manual, your advice is to run this simulation with a smaller time step and see if the results is equivalent. Would you advice something else for this purpose? Perhaps, a quantitative measure?<br /> Thank you in advance!<br /> Kind regards,<br /> Anastasiia. </p>
