SPOD

modulo_vki.modulo.ModuloVKI.SPOD(self, mode: str, F_S: float, n_Modes: int = 10, SAVE_SPOD: bool = True, **kwargs)

Unified Spectral POD interface.

Parameters:

• mode ({'sieber', 'towne'}) – Which SPOD algorithm to run.

• F_S (float) – Sampling frequency [Hz].

• n_Modes (int, optional) – Number of modes to compute, by default 10.

• SAVE_SPOD (bool, optional) – Whether to save outputs, by default True.

• **kwargs –

  For mode=’sieber’, accepts:

  • N_O (int): semi-order of the diagonal filter

  • f_c (float): cutoff frequency

  For mode=’towne’, accepts:

  • L_B (int): block length

  • O_B (int): block overlap

  • n_processes (int): number of parallel workers

Returns:

• Phi (ndarray) – Spatial modes.

• Sigma (ndarray) – Modal amplitudes.

• Aux (tuple) – Additional outputs.
