class hysop.operator.base.spatial_filtering.SpectralRestrictionFilterBase(plot_input_energy=None, plot_output_energy=None, **kwds)[source]

Bases: RestrictionFilterBase, SpectralOperatorBase

Base implementation for lowpass spatial filtering: small grid -> coarse grid using the spectral method.

Initialize a SpectralRestrictionFilterBase.

Parameters:

  • plot_input_energy (IOParams, optional, defaults to None) – Plot input field energy in a custom file.

  • plot_output_energy (IOParams, optional, defaults to None) – Plot output field energy in a custom file.

Notes

IOParams filename is formatted before being used:

{fname} is replaced with field name {ite} is replaced with simulation iteration id

If None is passed, no plots are generated.
