10User-defined output quantities<br>
11</font></h3>A very typical request of users is the
12calculation and
13output of
14quantities which are not part of PALM's standard output. The basic user
15interface includes a number of subroutines which allow the calculation
16of user-defined quantities and output of these quantities as 2d cross
17section or 3d volume data. The respective subroutines
18contain&nbsp;as
19an example code lines (written as comment lines) for calculating and
20output the square of the u-component velocity (note: this quantity
21could of course easily be calculated from the u-component by
22postprocessing the PALM output so that calculation within PALM is not
23necessarily required).<br><br>The
24rest of this chapter explains step-by-step how to modify/extend the
25default file user_interface.f90 in order to generate output of the
26quantity "square of the u-component". If more than one user-defined
27quantity shall be output, these steps have to be carried out in the
28same way for each of the quantities.<br><br><ol><li>The
29quantity has to be given a unique string identifier, e.g. <span style="font-style: italic;">'u2'</span>.
30This identifier must be different from the identifiers used for the
31PALM standard output (see list in description of parameter <a href="chapter_4.2.html#data_output">data_output</a>).
32To switch on output of this quantity, the user has to assign the string
33identifier to the parameter <a href="chapter_4.3.html#data_output_user">data_output_user</a>,
34eg.:<br><br><span style="font-family: monospace;">&nbsp;
35&nbsp; data_output_user</span> = <span style="font-style: italic;">'u2'</span>, <span style="font-style: italic;">&nbsp;'u2_xy_av'</span><br><br>The
36pure string <span style="font-style: italic;">'u2'</span>
37switches on the output of instantaneous 3d volume data. Output of cross
38section data and time averaged data is switched on by additionally
39appending the strings <span style="font-style: italic;">'_xy'</span>,
40<span style="font-style: italic;">'_xz'</span>, <span style="font-style: italic;">'_yz'</span>, and/or <span style="font-style: italic;">'_av'</span> (for a
41detailed explanation see parameter <a href="chapter_4.2.html#data_output">data_output</a>).<br><br></li><li>In
42order to store the quantities' grid point data within PALM, a 3d data
43array has to be declared in module <a href="chapter_3.5.1.html#user"><span style="font-family: monospace;">user</span></a>:<br><br><span style="font-family: monospace;">&nbsp; &nbsp; REAL,
