Hello, I'm trying to control 2 separate directional sources, pointing at different directions. I used the source.u_mask to locate the sources on the 3D grid , and defined different source.ux and source.uy source parameters . the spaceFirstOrder3D shows both sources propagating the 45deg. angle.
Please advise how to define a separate propagation angle per source.

Please advise also if it's possible to present a combined source.p and source.ux propagation.
Thanks!

Hi or,

You can control the direction by setting the appropriate weightings for the velocity terms (if you want dipole-type sources), by using a pressure source and controlling the phasing (see the Steering A Linear Array Example), or by controlling the source geometry so that it points in the desired direction.

Brad.
