Point Source
Use the Point Source node to add a point source to model a source of small dimensions. For a time-dependent model, it is possible to enter an expression that depend on time.
Point Source
How you define the Point source power depends on the choice of Band Input Type for The Acoustic Diffusion Equation.
If the Band Input Type is Flat (continuous) enter a Point source power qp (SI unit: W).
For Octave bands, 1/3 octave bands, or User defined bands, enter a Point source power qp (SI unit: W) in each row corresponding to the Band Number.
