If you're using the MATLAB code, it's almost trivial to implement. I'll make sure it's on the list of things to consider for the next release.</p> <p>If you're using the C++ code, the output data should already be streamed to disk, so shouldn't take up too much memory, at least not during the simulation.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/downsampling-sensor_data#post-6280 Tue, 06 Feb 2018 23:30:15 +0000 samantp 6280@http://www.k-wave.org/forum/ <p>Hi,<br /> I have 1025 sensors in my simulation and due to the requirements of a very low timestep, I need to have a very small timestep that essentially takes me to around 1,900,000 points per sensor. This can, of course, be quite taxing on computer RAM. Now, the running of the simulation doesn't take much time, I have a lot of computational power. However, the RAM always runs out simple due to the sheet number of time points I need.<br /> So, is it possible somehow to configure sensors to only record, for example, the pressure at every other timestep? Or every third timestep? This would greatly decrease the memory required to store sensor_data while all other parameters would remain the same.</p> <p>Thank you! </p>
