v128 v129 95 95 Cross sections extend through the total model domain. In the two horizontal directions all grid points with 0 <= i <= [[../inipar#nx|nx]]+1 and 0 <= j <= [[../inipar#ny|ny]]+1 are output so that in case of cyclic boundary conditions the complete total domain is represented. The location(s) of the cross sections can be defined with parameters [#section_xy section_xy], [#section_xz section_xz], and [#section_yz section_yz]. Assigning '''section_...''' = ''-1'' causes the output data to be averaged along the direction normal to the respective section.\\\\ 96 96 '''Output of user defined quantities:'''\\\\ 97 Beside the standard quantities from the above list, the user can output any other quantities. These have to be defined and calculated within the user-defined code (see [[ LINK 3.5.4]]). They can be selected for output with the user-parameter [[../userpar#data_output_user|data_output_user]] for which the same rules apply as for '''data_output'''. Output of the user defined quantities (time interval, averaging, selection of cross sections, etc.) is controlled with the parameters listed above and data are written to the same file(s) as the standard quantities.\\\\97 Beside the standard quantities from the above list, the user can output any other quantities.

After PALM has finished, the contents of these individual files are sampled into one final file using the program {{{combine_plot_fields.x}}} (automatically activated by '''mrun''').\\\\
