1421 | 1421 | For runs with constant eddy diffusivity (see [#km_constant km_constant]), this parameter can be used to assign the Prandtl number (ratio K,,m,, / K,,h,,). |

| 1435 | If **use_fixed_date** = .TRUE., the date does not change during a simulation. When PALM reaches 24:00:00 UTC, the time is set to 00:00:00 UTC without the date being changed. This affects, e.g., the solar position during a simulation.\\\\ |

| 1451 | If **use_fixed_time** = .TRUE., the time does not change during a simulation, i.e. PALM's clock would always show the value given by [#origin_date_time origin_date_time]. This results in the sun being fixed at a single position during the simulation. |
