    32  * '''clean_after_run:''' binary flag (0: no, 1: yes) indicating whether heavy-staff of the simulation (g.e.: {{{wrf.exs, rsl.}}}) should be removed from '{{{${WRF4G_RUN_LOCAL}}}}'. It should be desirable for debugging purposes the maintenance of these files on running place. (Default value is 1)
    33  * '''save_wps:''' binary flag (0: no, 1: yes) indicating whether boundary and initial conditions ({{{real.exe}}} output) should be preserved. They will be used if experiment launched again. (Default value is 0)

    3535== WRF-namelist parameters ==
    36 User provides namelist values. They will be over-written on {{{multiple_parameters}}} experiments (only the included parameters). User can modify any of the paramters of the namelist. It has to be the same name as in the {{{namelist.input}}} with a prefix-flag and the record to its belongs
    37  * '''Single valued; NI_[namelist_parameter_name]_ _[record]:''' {{{NI}}} flag indicating that [namelist_parameter_name] of record [record] has a single value
    38  * '''One value per all domains; NIN_[namelist_parameter_name]_ _[record]:''' {{{NIN}}} flag indicating that [namelist_paramter_name] of record [record] has the same value for all the domains of the experiment
    39  * '''One value per domain; NIM_[namelist_name]_ _[record]:''' {{{NIM}}} flag indicating that [namelist_paramter_name] of record [record] has a different value value for each the domains of the experiment

The name must be the same of the {{{namelist.input}}} entry, with a prefix-flag and the record to where belongs.

    42  * '''timestep_dxfactor:''' If present, the time step is computed as this fator times the dx in kilometers. Defaults to 6, as suggested by the WRF team for most applications. Under some circumstances (cfl problems) a lower value may be needed. In any case, the time step is adjusted to the higest value lower than {{{timestep_dxfactor}}} times {{{dx}}} fitting evenly in a 1 hour period.

    60 Multi-physics runs are activated when the {{{multiple_paramters}}} parameter is set to one. Three additional parameters allow you to configure the physics combinations to set up.
