<b>CIG Software Releases</b><br>
<br>
* Conman 2.0 - ConMan is a vectorized finite element program for the
<br>
solution of the equations of incompressible, infinite-Prandtl number <br>
convection in two dimensions, originally written by Arthur Raefsky, <br>
Scott King, and Brad Hager. See <br>
<a class="moz-txt-link-freetext" href="http://geodynamics.org/cig/software/packages/mc/conman/">http://geodynamics.org/cig/software/packages/mc/conman/</a> for source
code <br>
and manual.<br>
<br>
* SNAC 1.0 - SNAC (StGermaiN Analysis of Continua) is an updated <br>
Lagrangian explicit finite difference code for modeling a finitely <br>
deforming elasto-visco-plastic solid in 3D, released under the GNU <br>
General Public License. See <br>
<a class="moz-txt-link-freetext" href="http://geodynamics.org/cig/software/packages/long/snac/">http://geodynamics.org/cig/software/packages/long/snac/</a><br>
for source code and manual.<br>
<br>
<b>Software Bug Fix</b><br>
<br>
* PyLith 1.3.1- PyLith is a finite element code for the solution of <br>
visco-elastic/plastic deformation that was designed for lithospheric <br>
modeling problems. The latest version is primarily a bugfix release.
Two <br>
new minor features that were added include the addition of stages to <br>
PETSc logging to collect event logging in groups and the ability to set
<br>
the minimum shear wave speed in SCEC CVM-H queries. Bug fixes include <br>
honoring partitioning options (which were ignored in v1.3.0);
assembling <br>
of the Jacobian, residual, and fault sections across partitions (which <br>
caused errors in the computation of the change in tractions over the <br>
fault surface and errors while time-stepping in parallel); and omission
<br>
of closing the fault material property databases (which resulted in <br>
memory not being deallocated). See <br>
<a class="moz-txt-link-freetext" href="http://geodynamics.org/cig/software/packages/short/pylith/">http://geodynamics.org/cig/software/packages/short/pylith/</a> for source <br>

CIG Encourages Member Proposals to NSF; Solicits Feedback on CIG-II</b><br>
<br>
* CIG recently sent out a letter detailing plans for continuing its <br>
activities beyond the end of current funding and encouraging members of
<br>
the community to collaborate with computational scientists and seek <br>
funding from some relatively new NSF programs. We also want your <br>
feedback; read the Open Letter to the Community at <br>

<b>CIG is Seeking CIG-Enabled One-Pagers, Journal Articles</b><br>
<br>
* In preparation for the next phase of CIG, we are beginning a <br>
self-evaluation to understand the range of activities and impact of
CIG. <br>
As a useful mechanism (and a very nice way to highlight your own <br>
science), we are seeking bibliographic information and/or electronic <br>
copies of "One-Pagers" (that briefly describe an exciting piece of your
<br>
science that was made possible using CIG software or resources) or any <br>
published, in-press, or planned journal article or other publication <br>
that has been enabled by CIG or is contributing to the overall CIG <br>
effort. More details, an example one-pager, and forms for submitting <br>
your publication are at <br>

<b>Upcoming Meetings</b><br>
<br>
* CIG Business Meeting, Tuesday, December 16 (during AGU), 6-8:30 <br>
p.m., Parc 55 Hotel, Sienna Room (3rd Floor), San Francisco. You are <br>
invited to this public forum for members of the Geosciences community
to <br>
discuss the future development of CIG. Expect the main focus to be on <br>
plans for the future, including proposals for CIG-II. Meeting follows <br>
reception. Details at
<a class="moz-txt-link-freetext" href="http://geodynamics.org/cig/upcoming/business-mtg-08">http://geodynamics.org/cig/upcoming/business-mtg-08</a> .<br>
<br>
* Future of CIG Meeting, to be held in Spring 2009 (exact date <br>
TBA), Pasadena, CA. You are invited to this multiple-day meeting to <br>
discuss the future development of CIG. More details will be forthcoming
<br>
as plans are finalized.<br>
<br>
<b>Presentations and Posters from GeoMath08 Workshop Online</b><br>
<br>
* CIG Workshop on Mathematical and Computational Issues in the Solid
<br>
Earth Geosciences, Sept. 15-17, 2008, Santa Fe, NM. This CIG workshop <br>
brought together solid-earth geoscientists, mathematicians, <br>
computational and computer scientists to focus on specific issues <br>
arising from a range of solid-Earth dynamics problems that have proven <br>
both difficult and critical for progress in studying and modeling the <br>
dynamics of the planet. The Workshop Agenda now includes links to all <br>
the presentations and posters given at the workshop; see <br>

EC and SSC Committee Updates</b><br>
<br>
New EC and SSC Members - We are pleased to announce that the following <br>
people will be CIG's new officers filling 3-year terms:<br>
<br>
* EC: Bill Appelbe (VPAC)<br>
* SSC: Luc Lavier (U Texas at Austin), Andy Freed (Purdue), and <br>
Wolfgang Bangerth (reelected)<br>
<br>
In addition, SSC members elected Louise Kellogg (UC Davis) as their new
<br>
chair.<br>
<br>
We would also like to thank the outgoing members of the EC and SSC for <br>
their exemplary service and contributions to CIG. Brad Hager served for
<br>
two years on the EC, most recently serving as vice-chair and chair of <br>
the nominations committee and provided critical guidance during this <br>
time. Brad Aagaard has worked tirelessly in his three years on the SSC,
<br>
most recently as chair for the past year. We are indebted to his vision
<br>
and leadership. He has (and will continue) to provide fundamental <br>
contributions to short-term tectonics and the larger CFEM community as
a <br>
major developer of PyLith. Finally, we will miss Shijie Zhong who also <br>
served three years on the SSC and has provided critical leadership to <br>
the mantle convection community through organization of mantle <br>
convection workshops and in particular, his fundamental contributions
to <br>
Citcom and CitcomS. We look forward to continuing to work with Brad, <br>
Brad and Shijie as CIG plans for the future.<br>
