class SimpleTurbulenceSpectrum : public TurbulenceSpectrum

Defines the energy spectrum of simple power-law turbulence.

Public Functions

inline SimpleTurbulenceSpectrum(double Brms, double lMin, double lMax, double sIndex = 5. / 3)

The bend-over scale is set to 1000 times lMax to ensure to be in the inertial range. This should not be changed.

Parameters:

  • Brms – Root mean square field strength for generated field

  • lMin – Minimum physical scale of the turbulence

  • lMax – Maximum physical scale of the turbulence

  • sIndex – Spectral index of the energy spectrum in the inertial range
