Hello,
I have a problem working in 2D with the 'ReturnVelocity' option.
I have a single source point at (x,y) with a certain source.p0. Two sensor points are placed at (x, y-d) and (x, y+d) with d=10 or whatever.
As expected, the pressure in the two sensor points are exactly the same. Since the setup has been made symmetrically, I would also want the velocity vector in the y-direction to be the same (but opposite). But they are not, because I think the velocity at point (X, Y) is calculated with the difference in pressure between points (X, Y) and (X+1, Y) (for sensor_data.ux), right?. For example the velocity vector at (x, y-d) and (x, y+d-1) <b>are</b> the same.
Is there a 'neat solution' for this issue by for example using the pressure in points (X-1, Y) and (X+1, Y) in kspaceFirstOrder2D?
