Then you can assign the wire using your code, e.g., <pre><code>Nx = 50; Ny = 50; Nz = 50; c0 = 1500; cwire = 5900; sound_speed_map = c0 * ones(Nx, Ny, Nz); sound_speed_map(Nx/2, Ny/2, 1:end) = cwire; voxelPlot(sound_speed_map);</code></pre> Keep in mind if you are defining a scatterer right to the edge of the grid to place the perfectly matched layer (PML) outside your simulation by setting the optional input <code>'PMLInside', false</code>.
