The algorithm is based on:</p> <p><a href="http://bug.medphys.ucl.ac.uk/papers/2018-Treeby-CCP.pdf">B. E. Treeby, E. S. Wise, B. T. Cox, Nonstandard Fourier Pseudospectral Time Domain (PSTD) Schemes for Partial Differential Equations, Commun. Comput. Phys., 24 (3), pp. 623-634, 2018.</a></p> <p>So you could cite that along with k-Wave. </p> http://www.k-wave.org/forum/topic/memory-issues-and-a-possible-workaround#post-7790 Mon, 07 Sep 2020 01:15:39 +0000 DLam 7790@http://www.k-wave.org/forum/ <p>Thanks!<br /> I'm currently writing up a thesis on results that stem out of the thermal code in k-Wave. I'm wondering if you could point me to the relevant publication(s) that the thermal code was based on, or if it was original material, should I just cite the k-Wave toolbox?</p> <p>Best regards,</p> <p>Daniel </p> http://www.k-wave.org/forum/topic/memory-issues-and-a-possible-workaround#post-7726 Wed, 05 Aug 2020 20:30:29 +0000 Bradley Treeby 7726@http://www.k-wave.org/forum/ <p>Hi Daniel,</p> <p>Yes, you can just set the sensor input to <code>[]</code> (no sensor), and then query <code>kdiff.T</code>, <code>kdiff.cem43</code>, and <code>kdiff.lesion_map</code> at the end of the simulation. Note, you can likely use a much larger time step and still get an accurate answer.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/memory-issues-and-a-possible-workaround#post-7718 Sat, 01 Aug 2020 00:15:48 +0000 DLam 7718@http://www.k-wave.org/forum/ <p>Hi,</p> <p>I'm planning to use the kWaveDiffusion to simulate thermal diffusion. I will be switching between alternating between several source.Q arrays as I step through time, and I am using timesteps of 0.05 sec to simulate for a total time of 16 sec. </p> <p>However, currently the simulation runs out of memory -- I think this is because of the sensor_data field. If all I want at the end is the CEM43 lesion map and the final temperature map, should I just set sensor.mask to be FALSE everywhere, or is there something else I can do?</p> <p>Best regards,</p> <p>Daniel </p>
