Non-Uniform Time Sampling for Multiple-Frequency Harmonic Balance Computations [PDF]
A time-domain harmonic balance method for the analysis of almost-periodic (multi-harmonics) flows is presented. This method relies on Fourier analysis to derive an efficient alternative to classical time marching schemes for such flows.
