    v28 v29  
    2727  * [../initialization_parameters initialization parameters] steer the basic settings of the model run. They define e.g. the number of the grid points, the numerical schemes to be used, initial and boundary conditions to be applied, how the three-dimensional fields are initialized at the beginning of a model run (constant  value profiles or 1D-model-pre-run, the initial temperature profile etc.). These parameters apply to the total model run and thus **can not be changed with restart runs**! If one tries to change these values within the namelist input file of a restart run, then these changes are ignored (sole exception is the parameter [../initialization_parameters#initializing_actions initializing_actions], which must be given the value '' 'read_restart_data' '' for restart runs).
    2828       
    29   * [../d3par runtime parameters] generally steer actions to be carried out during a model run. One can select for example, at which times plot output should happen and which variables are to be written. Additionally one **must specify the time to be simulated**. Run parameters only apply to the actual run (job) and with **each restart run other values may be declared** (if runs are restarted automatically, parameters will usually keep their values, provided that the namelist input file was not changed by the user in the meantime).
     29  * [../runtime_parameters runtime parameters] generally steer actions to be carried out during a model run. One can select for example, at which times plot output should happen and which variables are to be written. Additionally one **must specify the time to be simulated**. Run parameters only apply to the actual run (job) and with **each restart run other values may be declared** (if runs are restarted automatically, parameters will usually keep their values, provided that the namelist input file was not changed by the user in the meantime).

    3131  * module parameters behave like run parameters. Module parameters determine the behavior of the additional modules. '''The respective modules are automatically switched on by putting their namelist groups into the parameter file.''' Instead of removing the specific namelist group, you can also switch off a module by setting the parameter {{{switch_off_module = .T.}}}. This parameter is defined for each namelist group, except {{{&initialization_parameters}}} and {{{&runtime_parameters}}}.
