The Spherical Wave Radiation node adds a radiation boundary condition for a spherical wave, for which you define the source location. If required, from the
Physics toolbar add an
Incident Pressure Field to model an incoming wave. This radiation condition allows an outgoing spherical wave to leave the modeling domain with minimal reflections. The geometry of the modeling domain should be adapted to have the outgoing spherical waves coincide with the boundary. This is in order to minimize spurious reflections.
Enter coordinates for the Source location r0 (SI unit: m). The defaults are 0 m.
