Sentence examples for modeled a harmonic from inspiring English sources
Adaptive harmonic spectral decomposition [26] has modeled a harmonic structure in a different way.
The unsteady aerodynamic response of the blades to self-excited vibrations and gust response is modeled using a harmonic balance method, which allows one to model the entire wheel using complex periodic boundary conditions and a computational grid spanning a single sector (symmetry group).
