Last change on this file since 124 was 108, checked in by letzel, 17 years ago
  • Improved coupler: evaporation - salinity-flux coupling for humidity = .T.,

avoid MPI hangs when coupled runs terminate, add DOC/app/chapter_3.8;

  • Optional calculation of km and kh from initial TKE e_init;
  • Default initialization of km,kh = 0.00001 for ocean = .T.;
  • Allow data_output_pr= q, wq, w"q", w*q* for humidity = .T.;
  • Bugfix: Rayleigh damping for ocean fixed.
  • Property svn:keywords set to Id

26<h3 style="line-height: 100%;">3.7 Optional software packages</h3>
27
28<p style="line-height: 100%;">Starting from version 2.1
29PALM includes
30so-called software packages which can be used optionally. These
31software packages are part of the model, but they are not compiled with
32the default model
33installation (actually, the routines of the corresponding packages are
34compiled within the installation, but these subroutines are empty,
35i.e. they do not contain any executable statements). Thus the
36compilation time as well as the memory demand of the model is limited
37to the real needs. </p>
38
39<p style="line-height: 100%;">To use software packages in
40a model run,
41they must be requested with <b>mrun</b> option <tt><font style="font-size: 10pt;" size="2">-p</font>.</tt>
42Then the subroutines belonging to the respective package are
43additionally compiled for the run (and the respective restart
44runs; the filenames of these subroutines are also displayed on the
45terminal after <b>mrun</b> has been called). If one wants
46to use e.g.
47the two packages with the names
48<tt>package1</tt> and <tt>package2</tt>, then
49the <b>mrun</b> call
50has to be: </p>
51
52<ul>
53 
54  <p style="line-height: 100%;"><tt><font style="font-size: 10pt;" size="2">mrun ... -p
55&ldquo;package1 package2&rdquo; </font>.</tt></p>
56
57</ul>
58<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>
59<p style="line-height: 100%;">Further package
60names can be added to
61the list, separated by blanks. If the respective packages permit user
62steering, the appropriate parameters must be given at the end of
63the file <a href="chapter_3.4.html#PARIN">PARIN</a>.
64They must be given <b>before</b> possible user-defined
65parameters!
66Each package requires its own NAMELIST group. The respective NAMELIST
67group name is given in the table below. For the example above one
68would have to add the following lines to PARIN (example): &nbsp; </p>
69
70<ul>

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

74&ldquo;abcd&rdquo; /</font></tt><font style="font-size: 10pt;" size="2"> </font> </p>

76  <p style="line-height: 100%;"><tt><font style="font-size: 10pt;" size="2">&amp;namelist_packagename2
