Function Documentation

inline void crpropa::initTurbulence(ref_ptr<Grid3f> grid, double Brms, double lMin, double lMax, double alpha = -11 / 3., int seed = 0)

Create a random initialization of a turbulent field.

Parameters:

• grid – grid on which the turbulence is calculated

• lMin – Minimum wavelength of the turbulence

• lMax – Maximum wavelength of the turbulence

• alpha – Power law index of <B^2(k)> ~ k^alpha (alpha = -11/3 corresponds to a Kolmogorov spectrum)

• Brms – RMS field strength

• seed – Random seed
