[Webnucleo] Libnucnet data file

[Announce list for the Webnucleo project.]

On May 18, 2009 libnucnet version 0.4 was released:

http://www.ces.clemson.edu/pipermail/webnucleo/2009-May/000046.html

A key feature of the new release is the link to the new arrow solver
available in wn_matrix version 0.8 and later versions.  This allows
libnucnet 0.4 codes to run r-, s-, and p-process calculations efficiently.

In order to keep the distribution tarball from getting too large, the
libnucnet 0.4 distribution included data files only appropriate for
networks up to and including germanium (Z = 32).  To run larger network
calculations, it is necessary to have larger data files.  It is not
webnucleo.org's intention to maintain nuclear and reaction databases;
nevertheless, we have constructed a data file appropriate for large
network calculations.

This data file for large nuclear network calculations is available at

http://www.webnucleo.org/experimental/mbradle/download/network_data/example_single_zone_full.xml

It can be downloaded and used directly or can be used over the web.  For
example, you can run from your libnucnet/0.4/src/examples/ directory:

./example4
http://www.webnucleo.org/experimental/mbradle/download/network_data/example_single_zone_full.xml

to get the list of nuclei,

./example14
http://www.webnucleo.org/experimental/mbradle/download/network_data/example_single_zone_full.xml

to get the list of reactions, and

./example41
http://www.webnucleo.org/experimental/mbradle/download/network_data/example_single_zone_full.xml
0 0 0 10. 1.e10 0.1 10. 20

to run a single zone calculation.  It is also possible to run a single
zone calculation from a table:

./example43
http:/www.webnucleo.org/experimental/mbradle/download/network_data/example_single_zone_full.xml
../../data_pub/zone_ascii.txt ../../data_pub/mass_fractions.txt 30. 20

although you will have to comment out the validation call in the example
code.

We have also written some stylesheets to extract nuc, reac, and net xml
files to your local computer should you prefer to work with those.  You
can run the commands:

xsltproc
http://www.webnucleo.org/experimental/mbradle/download/xsl_pub/extract_nuc.xsl
http://www.webnucleo.org/experimental/mbradle/download/network_data/example_single_zone_full.xml
> example_nuc_full.xml

xsltproc
http://www.webnucleo.org/experimental/mbradle/download/xsl_pub/extract_reac.xsl
http://www.webnucleo.org/experimental/mbradle/download/network_data/example_single_zone_full.xml
> example_reac_full.xml

xsltproc
http://www.webnucleo.org/experimental/mbradle/download/xsl_pub/extract_net.xsl
http://www.webnucleo.org/experimental/mbradle/download/network_data/example_single_zone_full.xml
> example_net_full.xml

We view this as a temporary solution until a more standard data set is
available in xml format (for example, reaclib).  If you have suggestions
about the future possible disposition of the data, we'd appreciate hearing
about them.  To communicate your ideas with us, we suggest you send an
email to webnucleo-bugs at ces.clemson.edu, the Webnucleo.org bug and
features request list.  Thanks for your continued interest in libnucnet,
and best wishes.
