From my understanding, the minimum frequency depends on the size of the computational domain, and the maximum supported frequency is determined by the grid size.</p> <p>My question is: Is the frequency response in this range linear? Additionally, would the smoothing function affect this in any way?</p> <p>If the medium properties, such as the speed of sound and density, are fixed, would the frequency response still depend on the acoustic geometry or the amplitude of the initial pressure?<br /> Thanks </p>
