Hi. I see that the makeGrid command is needed for the program, and that the grid it makes is centered on 0,0. It would be nice if I could make a model who's origin is more convenient, like at the middle of the transducer or target, or focus. Is that possible? Thanks.

Does the origin of the grid need to be at 0,0 (Cartesian)?

Hi ad000000,
Most of the k-Wave inputs are grid based (e.g., the source mask), so externally, you can assume any coordinate system origin. However, the inputs that are Cartesian based (e.g., using a Cartesian sensor mask, or using functions such as
makeCartSphere) assume the origin is in the centre of the grid at(Nx/2, Ny/2, Nz/2), and it's not currently possible to change this.Brad.
