v7 v8 19 19 Parameters belonging to the group {{{inipar}}} are first read by PALM. These are the initialization parameters. Second, the so-called run parameters belonging to the group {{{d3par}}} are read in, then the parameters for steering the optional software packages (group {{{packagename}}}, the string "{{{packagename}}}" must be replaced by the NAMELIST group name of the respective package) as well as user-defined parameters (group {{{userpar}}}). The four groups must be given in this order, the last groups, {{{packagename}}} and {{{userpar}}}, may be omitted. If several software packages are selected ([../packages see "Optional software packages"]), further NAMELIST groups may be inserted before the group {{{userpar}}}. 20 20 21 The '''initialization''', '''run''' and '''package ''' parametersdiffer as follows:21 The '''initialization''', '''run''' and '''package parameters''' differ as follows: 22 22 23 23 * The '''[../inipar initialization parameters]''' are steering 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 [../inipar#initializing_actions initializing_actions], which must be given the value '' 'read_restart_data' '' for restart runs).
