timestep.f90:

  • consider 2*Km within diffusion criterion as Km is considered twice within the diffusion of e,
  • in RANS mode, instead of considering each wind component individually use the wind speed of 3d wind vector in CFL criterion
  • do not limit the increase of dt based on its previous value in RANS mode

other:

  • remove dt_old
