Theory
Each receiver has a name and x, y, z in mm. During the sweep the pressure of the run's own excitation is interpolated at the point with the P2 shape functions of the tetrahedron that contains it. The method and its check are in Additional acoustic results: receivers, section power, dissipation, flow effect.

Inside the model
A point outside the acoustic model gives no value; the log lists it.
