Numerical Study of Eigenvector Deflation to Accelerate the WaveHoltz Method

Daniel Appelo, William D. Henshaw, Zhichao Peng

We present a numerical study of eigenvector deflation as a means of accelerating the WaveHoltz method for solving the Helmholtz equation. For energy-conserving (Dirichlet or Neuman…
