Introduction • Harmonic Analysis solution with Full method can be computationally expensive. • The frequency-sweep harmonic analysis based on the Krylov Method provides a high- performance solution for forced-frequency simulations in acoustic analyses. • The Krylov method uses the full matrices but with the following differences: - A Krylov Subspace is built at the given frequency (defaults to the middle of the requested frequency range) and reduce the system matrices and loading on the entire frequency range. - Solve the reduced system - Expand the results to compute the harmonic response
