    22252225Time step for the 3d-model (in s).\\\\
    22262226By default, (i.e. if a Runge-Kutta scheme is used, see [#timestep_scheme timestep_scheme]) the value of the time step is automatically calculated after each time step in order to follow the Courant Friedrichs Levy (CFL) criterion. This value is then used for the next step.\\\\
    2227 If '''dt''' is assigned a value, then the time step is fixed to this value throughout the whole run (whether it fulfills the time step criteria or not). However, changes are allowed for restart runs, because '''dt''' can also be used as a [../d3par run parameter].\\\\
     2227If '''dt''' is assigned a value, then the time step is fixed to this value throughout the whole run (whether it fulfills the time step criteria or not). However, changes are allowed for restart runs, because '''dt''' can also be used as a [../runtime_parameters run parameter].\\\\
    22282228In case that the automatically calculated time step meets the condition\\\\
    22292229      '''dt''' < 0.00001 * [../runtime_parameters#dt_max dt_max] (with dt_max = 20.0)\\\\
