13can add their own (modified) user-interface to a PALM-run by carrying
14out the following steps:</p><ol><li>Copy the default
15(empty) user-interface (file<span style="font-family: Courier New,Courier,monospace;">
16user_interface.f90</span>) to a directory of your choice, e.g.:<br><br><span style="font-family: Courier New,Courier,monospace;">&nbsp;
17&nbsp;cd ~/palm/current_version</span><br style="font-family: Courier New,Courier,monospace;"><span style="font-family: Courier New,Courier,monospace;">&nbsp;
18&nbsp;mkdir -p USER_CODE/example</span><br style="font-family: Courier New,Courier,monospace;"><span style="font-family: Courier New,Courier,monospace;">&nbsp;
19&nbsp;cp trunk/SOURCE/user_interface.f90&nbsp;
20USER_CODE/example/user_example.f90</span><br></li><li>Set
21an additional path in the configuration file<span style="font-family: Courier New,Courier,monospace;">
22.mrun.config </span>to allow <span style="font-weight: bold;">mrun
23</span>to find and include this file:<br><br><span style="font-family: Courier New,Courier,monospace;">&nbsp;
24&nbsp;%add_source_path&nbsp;&nbsp;
25$base_directory/USER_CODE/$fname</span><br><br>The
26default configuration file (<span style="font-family: Courier New,Courier,monospace;">trunk/SCRIPTS/.mrun.config.default</span>)
27already includes this setting.</li><li>Modify the interface
28routines according to your needs.</li><li>Start a PALM run
29by executing<br><br><span style="font-family: Courier New,Courier,monospace;">&nbsp;
30&nbsp;mrun -d example ...</span><br><br>The file<span style="font-family: Courier New,Courier,monospace;">
31user_example.f90 </span>will be automatically compiled within
32the job and will replace PALM&lsquo;s default user-interface.<br></li></ol>The
33above method with including<span style="font-family: Courier New,Courier,monospace;"> $fname </span>in
34the additional source path allows to use different user-interfaces for
35different runs at the same time. Just store the respective
36interface-files in subdirectories<span style="font-family: Courier New,Courier,monospace;">
37USER_CODE/abcd</span>,<span style="font-family: Courier New,Courier,monospace;">
38USER_CODE/cdef</span>, etc. and start <span style="font-weight: bold;">mrun</span> with option
39&ldquo;<span style="font-family: Courier New,Courier,monospace;">-d
40abcd</span>&ldquo;, &ldquo;<span style="font-family: Courier New,Courier,monospace;">-d cdef</span>&ldquo;,
41etc.<br><br><span style="font-weight: bold;">The
42modified user-interface file cannot be pre-compiled by using mbuild!</span><br><br>While
43programming user-defined code,
44errors are frequently made. Possible ways of error
45tracing are described in the next chapter. <br><p style="line-height: 100%;">
