**v8.22.100** AHLV100 - Anechoic Output Waveguide
=========================================================

**Summary:**

A rectilinear waveguide with anechoic output, with rigid walls, whose propagation medium is "normal" air, is excited by a harmonically vibrating piston.

Using an acoustic formulation, the acoustic pressure field of the harmonic response is calculated for 13 different models. The results are tested at 2 points at the entrance and 2 points at the exit.

They make it possible to validate the stiffness, mass, damping (impedance) matrices, the source vector (imposed normal speed) as well as the post-processing operators.

The reference results come from an analytical calculation.
