This allows the use of the FFT to calculate spatial gradients. You can run simulations in an axisymmetric coordinate system using <code>kspaceFirstOrderAS</code>, but the x/r coordinates are still on a rectangular mesh.</p> <p>Brad. </p> http://www.k-wave.org/forum/topic/how-can-i-creat-a-circular-kgrid-in-2d-space#post-7878 Fri, 09 Oct 2020 02:41:19 +0000 yu haoyng 7878@http://www.k-wave.org/forum/ <p>Hi,<br /> I found that the function,kWaveGrid(Nx,dx,Ny,dy), seems only be able to creat a rectangle kgrid. Is there a possible way to make a circular kgrid?</p> <p>Thanks:&gt; </p>
