Perhaps reducing the number of grid points, shrinking the sensor mask (if applicable), casting variables to 32-bit precision, avoiding saving time-varying pressures and velocities (as well as acoustic intensities of any kind), or a combination of all of these could be necessary.</p> <p>HDF5 files in general can be imported into MATLAB using <code>h5read()</code>. In the case of k-Wave, this should only be necessary if you are working directly with the <code>kspaceFirstOrder3D-OMP/-CUDA</code> binaries, rather than using the <code>kspaceFirstOrder3DC/G()</code> wrappers. </p> http://www.k-wave.org/forum/topic/computer-restarts-while-running-the-nonlinear-program#post-7109 Tue, 29 Oct 2019 13:37:17 +0000 ykx 7109@http://www.k-wave.org/forum/ <p>Hi, everyone! I use k-Wave to simulate the nonlinear field of the phased array.</p> <p>Recently, when the program is nearly done , my computer has no response.Several hours later, the matlab is closed and the cache file(H5 form) is 83.5GB. </p> <p>I ran the same program before and after the "no response" situation, the result was gotten. However, I can not have the result now.</p> <p>How can I stop matlab or my computer crashing? And how can I convert the H5 file to MAT file(if possible)? </p> <p>Thanks!<br /> Ykx </p>
