24<h3 style="line-height: 100%;">3.7 Optional software packages</h3>
25
26<p style="line-height: 100%;">Starting from version 2.1
27PALM includes
28so-called software packages which can be used optionally. These
29software packages are part of the model, but they are not compiled with
30the default model
31installation (actually, the routines of the corresponding packages are
32compiled within the installation, but these subroutines are empty,
33i.e. they do not contain any executable statements). Thus the
34compilation time as well as the memory demand of the model is limited
35to the real needs. </p>
36
37<p style="line-height: 100%;">To use software packages in
38a model run,
39they must be requested with <b>mrun</b> option <tt><font style="font-size: 10pt;" size="2">-p</font>.</tt>
40Then the subroutines belonging to the respective package are
41additionally compiled for the run (and the respective restart
42runs; the filenames of these subroutines are also displayed on the
43terminal after <b>mrun</b> has been called). If one wants
44to use e.g.
45the two packages with the names
46<tt>package1</tt> and <tt>package2</tt>, then
47the <b>mrun</b> call
48has to be: </p>
49
50<ul>
51 
52  <p style="line-height: 100%;"><tt><font style="font-size: 10pt;" size="2">mrun ... -p
53&ldquo;package1 package2&rdquo; </font>.</tt></p>
54
55</ul>
56<p style="line-height: 100%;">Starting from version 3.2, the particles-package is part of the default model, so it does not have to be switched on using <span style="font-weight: bold;">mrun</span>-option <span style="font-family: Courier New,Courier,monospace;">-p</span>. However, the respective parameters have still to be set by using the NAMELIST group <span style="font-family: Courier New,Courier,monospace;">particles_par</span>.</p>
57<p style="line-height: 100%;">Further package
58names can be added to
59the list, separated by blanks. If the respective packages permit user
60steering, the appropriate parameters must be given at the end of
61the file <a href="chapter_3.4.html#PARIN">PARIN</a>.
62They must be given <b>before</b> possible user-defined
63parameters!
64Each package requires its own NAMELIST group. The respective NAMELIST
65group name is given in the table below. For the example above one
66would have to add the following lines to PARIN (example): &nbsp; </p>
67
68<ul>

70  <p style="line-height: 100%;"><tt><font style="font-size: 10pt;" size="2">&amp;namelist_packagename1

72&ldquo;abcd&rdquo; /</font></tt><font style="font-size: 10pt;" size="2"> </font> </p>
73
74  <p style="line-height: 100%;"><tt><font style="font-size: 10pt;" size="2">&amp;namelist_packagename2
