Example of results obtained with a hybrid FEM-spectral approach for modeling a fluid loaded cylindrical shell coupled to internal frames in the mid-frequency range: (a) vibratory field on the cylindrical shell; (b) spectral decomposition of the vibration field; (c) radiated pressure in the far field. Results for a harmonic radial point force on the shell at 1 kHz [19, 20].
