This paper describes the details of a novel numerical finite-element-based analysis procedure and a resulting code for the simulation of the acoustics phenomenon arising from aeroelastic interactions. Both computational fluid dynamics and structural simulations are based on finite element discretisation employing unstructured grids. The sound pressure level on structural surfaces is calculated from the root mean square of the unsteady pressure, and the acoustic-wave frequencies are computed from a fast Fourier transform of the unsteady pressure distribution as a function of time. The newly developed tool proves to be unique, as it is designed to analyze complex practical problems involving computations in a routine fashion.
