<p>All simulations in k-Wave are performed using regularly-spaced rectangular grids. 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>

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:>
