+'''NOTE:''' The Kolmogorov length scale η is defined by  (ν^3^/ε)^1/4^ with ν being the kinematic, molecular viscosity and ε being the turbulent kinetic energy dissipation rate. However, as LES is not resolving the smallest scales of the velocity field the direct determination of the dissipation rate and therefore of the Kolmogorov length scale is not possible. Only in case of DNS, η should be outputted and interpreted accordingly.    
 \\\\
 Beyond that, initial profiles (t=0) of some variables can additionally be output (this output is only done once with the first plot output and not repeated with the profile output at later times). The names of these profiles result from the ones specified above led by a hash "#".  Allowed values are:
