|---|
| 20 | <p style="line-height: 100%;">Starting from version 2.1 PALM includes |
|---|
| 21 | so-called software packages which can be used optionally. These |
|---|
| 22 | software packages are part of the model, but they are not compiled with |
|---|
| 23 | the default model |
|---|
| 24 | installation (actually, the routines of the corresponding packages are |
|---|
| 25 | compiled within the installation, but these subroutines are empty, |
|---|
| 26 | i.e. they do not contain any executable statements). Thus the |
|---|
| 27 | compilation time as well as the memory demand of the model is limited |
|---|
| 28 | to the real needs. </p> |
|---|
| 29 | <p style="line-height: 100%;">To use software packages in a model run, |
|---|
| 30 | they must be requested with <b>mrun</b> option <tt><font |
|---|
| 31 | style="font-size: 10pt;" size="2">-p</font>.</tt> |
|---|
| 32 | Then the subroutines belonging to the respective package are |
|---|
| 33 | additionally compiled for the run (and the respective restart |
|---|
| 34 | runs; the filenames of these subroutines are also displayed on the |
|---|
| 35 | terminal after <b>mrun</b> has been called). If one wants to use e.g. |
|---|
| 36 | the two packages with the names |
|---|
| 37 | <tt>package1</tt> and <tt>package2</tt>, then the <b>mrun</b> call |
|---|
| 38 | has to be: </p> |
|---|
| 39 | <ul> |
|---|
| 40 | <p style="line-height: 100%;"><tt><font style="font-size: 10pt;" |
|---|
| 41 | size="2">mrun ... -p package1 package2 </font>.</tt></p> |
|---|
| 42 | </ul> |
|---|
| 43 | <p style="line-height: 100%;">Further package names can be added to |
|---|
| 44 | the list, separated by blanks. If the respective packages permit user |
|---|
| 45 | steering, the appropriate parameters must be given at the end of |
|---|
| 46 | the file <a href="chapter_3.4.html#PARIN">PARIN</a>. |
|---|
| 47 | They must be given <b>before</b> possible user-defined parameters! |
|---|
| 48 | Each package requires its own NAMELIST group. The respective NAMELIST |
|---|
| 49 | group name is given in the table below. For the example above one |
|---|
| 50 | would have to add the following lines to PARIN (example): </p> |
|---|
| 51 | <ul> |
|---|
| 52 | <p style="line-height: 100%;"><tt><font style="font-size: 10pt;" |
|---|
| 53 | size="2">&namelist_packagename1 var1 = 1,0, var2 = |
|---|
| 54 | abcd /</font></tt><font style="font-size: 10pt;" size="2"> </font> </p> |
|---|
| 55 | <p style="line-height: 100%;"><tt><font style="font-size: 10pt;" |
|---|
| 56 | size="2">&namelist_packagename2 var3 = .TRUE., |
|---|
| 57 | var4 = 0 /</font></tt></p> |
|---|
| 58 | </ul> |
|---|
| 59 | <p style="margin-bottom: 0cm; line-height: 100%;">The following |
|---|
