   Hi,
   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?

   Thanks:>

   Hi Yu,

   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 kspaceFirstOrderAS, but the x/r coordinates are still on a rectangular mesh.

   Brad.
