PAFEC VibroAcoustics  Transient analysis of a horn 

The example below shows results of a transient analysis of a horn.
The mouth of the horn is mounted in an infinite rigid baffle.
The piston at the throat has a single pulse prescribed as the displacement history.


An axisymmetric model is used. Acoustic finite elements model
the air inside the horn and extend out to a spherical surface. Wave
envelope elements then model the remainder of the half space.
