v2.04.124 SDLV124 — Volume pad subject to harmonic pressure

Summary:

The objective of this test case is to validate the harmonic calculation of a rectangular block modelled in volume elements subjected to sinusoidal pressure. The harmonic response calculation is also validated on a matrix projected on a modal basis.

The reference solution is obtained using a transient calculation carried out on the same model.
