Contents Chapter 41: Acoustic Analysis of a Viscothermal Resonator | Print page 41.6. Analysis and Solution ControlsA full harmonic analysis is performed from 1000 to 2000 Hz in 10 Hz increments as shown in the figure below. The acoustic load is applied as a step with constant unit velocity across the frequency range.Figure 41.8: Full Harmonic Analysis « 41.5. Boundary Conditions and Loading 41.7. Results and Discussion »
