    • Diffusion Validation I
      • This notebbok simulates a diffusion process in a homogenous background magnetic field. The diffusion tensor is anisotropic, meaning the parallel component is larger than the perpendicular component (\(\kappa_\parallel = 10\cdot\kappa_\perp\)).
      • Distribution in x, y and z
      • Use the absolute distance from origin \(|x|, |y|, |z|\) and compare to analytical expectations.
      • Calculate the pValue of the \(\chi^2\)-test to prove the visual stattement from above.
    • first example code for use of densitys
      • all densitys are seperated in atomic hydrogyn (HI), ioninised hydrogyn (HII) and molecular hydrogn (H2)
        • this example contains
        • first we start with the use of a constant density
      • the ConstantDensity can be adjusted to new values and the useage of several parts can be chosen
      • the output of the getDensity and getNucleonDensity depends on the activity of the types. Only acitvated types are used for summing up
