prognostic_equations include the respective wall_*flux in the parameter list of
calls of diffusion_s. Same as before, only the values of wall_heatflux(0:4)
can be assigned. At present, wall_humidityflux, wall_qflux, wall_salinityflux,
wall_scalarflux are kept zero. diffusion_s uses the respective wall_*flux
instead of wall_heatflux. This update serves two purposes:

  • it avoids errors in calculations with humidity/scalar/salinity and prescribed

non-zero wall_heatflux,

  • it prepares PALM for a possible assignment of wall fluxes of

humidity/scalar/salinity in a future release.

Bugfix: assignment of fluxes at walls

Updates to documentation:

Default for mrun options -q and -n is "sla3" for lctit. Queues bes1 and bes2
removed. DOC/misc/Tsubame.html updated.

9User-defined output quantities<br>
10</font></h3>A very typical request of users is the
11calculation and
12output of
13quantities which are not part of PALM's standard output. The basic user
14interface includes a number of subroutines which allow the calculation
15of user-defined quantities and output of these quantities as (horizontally averaged) <a href="#vertical_profiles">vertical profiles</a>, <a href="#time_series">time series</a>, <a href="#2D_and_3D">2d cross
16section</a> or <a href="#2D_and_3D">3d volume data</a>. The respective subroutines
17contain sample code lines (written as comment lines) for defining, calculating and
18output of such quantities.<br><br>Output times, averaging intervals, etc. are steered by the same variables as used for the standard PALM output quantities, e.g. <a href="chapter_4.2.html#dt_data_output">dt_data_output</a>.<br><br>The
19rest of this chapter explains step-by-step how to modify/extend the
20default file user_interface.f90 in order to generate the respective output.<br><br><br><h4><a name="vertical_profiles"></a>Output of vertical profiles</h4>This example shows the output of the
21quantity "turbulent resolved-scale horizontal momentum flux" (u*v*). If more than one user-defined
22quantity shall be output, the following steps have to be carried out in the
23same way for each of the quantities.<br><br><ol><li>The
24quantity has to be given a unique string identifier, e.g. <span style="font-style: italic;">'u*v*'</span>.
25This identifier must be different from the identifiers used for the
26PALM standard output (see list in description of parameter <a href="chapter_4.2.html#data_output_pr">data_output_pr</a>).
27To switch on output of this quantity, the user has to assign the string
28identifier to the parameter <a href="chapter_4.3.html#data_output_pr_user">data_output_pr_user</a>,
29eg.:<br><br><span style="font-family: monospace;">&nbsp;
