Convergence Acceleration of the Harmonic Balance Method Using a Time-Level Preconditioner

What is it about?

Simulations of fluid flows that are time-periodic are useful in many engineering fields. In this paper, one simulation approach tailored for time-periodic flows, known as the Harmonic Balance method, is analysed. The paper brings valuable insights into the properties of the Harmonic Balance method, as well as ways to use the method efficiently.
