Abstract:

In this paper, a new iterative grid selection strategy for the Time-Mapped Harmonic Balance (TMHB) method is presented. This strategy is referred to the adaptive grid methods, which tracks the rapid transitions and constructs a smooth time-map function. The theoretical analysis and experiment results of this grid selection strategy are presented. The results demonstrate that the new strategy solves the problem of numerical instability and achieves accurate results in the TMHB method.
