However, we do intend to write <code>kspaceFirstOrder2DG</code> and <code>kspaceFirstOrder2DC</code> functions that call the 3D code with Nz = 1 at some point. You could try this now (by calling <code>kspaceFirstOrder3DG</code> with Nz = 1), but I suspect some things might break. In any case, to turn off the z-direction PML, use<code>&#39;PMLAlpha&#39;, [2, 2, 0]</code>.</p> <p>Hope that helps,</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/c-binary-in-2d#post-5977 Wed, 07 Jun 2017 15:04:34 +0000 nicoq 5977@http://www.k-wave.org/forum/ <p>Hello,</p> <p>I've succesfully used k-wave with the C++ binary for complex 3D models in previous projects. </p> <p>However, for a very high frequency project (&gt; 200 MHz), I've to come back to a 2D model since the grid size for my problem is at least 4096 x 8192 (in fact I should go up to 8192 x 16384) .</p> <p>In order to reduce the computation time, I'like to use the C++ (or CUDA) implementation of k-wave, but this one is only available for 3D computation.</p> <p>So, I'd like to know:<br /> - if a 2D extension of the C++ (or CUDA) binaries is available ?<br /> - if not, is it scheduled for a future release ?<br /> - Otherwise, should I use a 3D grid with a grid dimension of 1 wrt to z ?<br /> - In this case how to remove the PML in the 3rd dimension ?<br /> - Or what would be the minimal grid dimension to use ?</p> <p>Thanks a lot for your amazing work !</p> <p>Nicolas </p>
