Dear Anindya,

Discrete Fourier analysis is already performed by BOS Fluids on the sawtooth function of suction or discharge. In mechanical response analysis, the shaking forces from acoustical analysis are used to perform a standard harmonic mechanical analysis.

Since BOS Fluids produces three dimensional plots of the unbalanced force distribution, it is typically easy for the user to inspect those plots and decide which of the force components should be used in the mechanical harmonic analysis.

My question is, what is the input value of harmonic force in CAESAR II dynamic analysis?
