These notebooks walk through kspace usage end-to-end.

• Power Spectra and Gaussian Random Fields
• Vector Field Decomposition
• Another Power Spectrum Example
• Computing a Power Spectrum from a Hydrodynamic Simulation

• Power Spectra and Gaussian Random Fields — build power spectra with different dissipation scales, generate GRF realizations, and check the recovered power spectrum against the input model.

• Vector Field Decomposition — generate vector field realizations and project out the divergence-free (solenoidal) component.

• Another Power Spectrum Example — reduce a full 3D gridded power spectrum to a 1D radially-binned spectrum and compare to the analytic integral.

• Computing a Power Spectrum from a Hydrodynamic Simulation — load a yt sample dataset, extract a uniform-grid field, and compute its power spectrum with FourierAnalysis.
