Use the Dipole Source node to add the domain source term qd to the governing equation. This source is typically stronger in two opposite directions. In advanced models, this term can, for example, be used to represent a uniform constant background flow convecting the sound field. Add this node from the More> submenu.Enter coordinates for the Dipole source qd (SI unit: N/m3). These are the individual components of the dipole source vector. The defaults are 0 N/m3.
