CIG Software Releases</b>
<br>
<br>
* CitcomS 3.1.1 - CitcomS is a finite element code designed to solve
thermal convection problems relevant to Earth's mantle. In mid-June,
the 3.1.0 release debuted, which offered many new features and fixed
several bugs in the code and manual (the release announcement at
<a class="moz-txt-link-freetext"
href="http://geodynamics.org/pipermail/cig-all/2009-June/000116.html">http://geodynamics.org/pipermail/cig-all/2009-June/000116.html</a>
has full
details). The bug-fix 3.1.1 release followed two weeks later to add
files missing from Cookbook 10. See
<a class="moz-txt-link-freetext"
href="http://geodynamics.org/cig/software/packages/mc/citcoms/">http://geodynamics.org/cig/software/packages/mc/citcoms/</a>
for source
code and manual. You can also run this latest version of CitcomS on the
TeraGrid; see <a class="moz-txt-link-freetext"

.<br>

* PyLith 1.4.0 - PyLith is a finite element code for the solution of
visco-elastic/plastic deformation that was designed for lithospheric
modeling problems. New features adds several new features to PyLith,
including a Power-law nonlinear bulk rheology; integration with PETSc
nonlinear solvers; automatic nondimensionalization of all parameters;
parsing of units in spatial database files; a common time-dependent
formulation for Dirichlet, Neumann, and point force boundary
conditions; pylithinfo, a diagnostic utility that dumps the current
hierarchy of PyLith parameters to a file; and replacement of
Pyrex/Pyrexembed with SWIG. Nondimensionalization of the problem
restores the symmetry of the Jacobian matrix, which significantly
reduces memory use (the release announcement at

has full
details). All PyLith users should switch to this latest release.The
manual has also been updated for the new features and revised based on
feedback from users. See

for source
code, binaries, and manual.<br>
<br>
* SNAC 1.1.0 - SNAC (StGermaiN Analysis of Continua) is an updated
Lagrangian explicit finite difference code for modeling a finitely
deforming elasto-visco-plastic solid in 3D. In this update,
post-processing is improved; checkpointing is activated; the code
generating restart files is improved thanks to Colin Stark; a new
plugin (hillSlope) for landslide problems is included, donated by Colin
Stark; and unnecessary dependencies are disabled and obsolete plugins
removed. See <a class="moz-txt-link-freetext"
href="http://geodynamics.org/cig/software/packages/long/snac/">http://geodynamics.org/cig/software/packages/long/snac/</a>
for source code and updated manual.<br>
<br>
<b>CIG-II Draft Online; Request Comments, Suggestions</b><br>
<br>
* The Proposal Writing Committee (PWC) is soliciting community
review, comments, and suggestions on its draft proposal documents for
CIG II, which they are preparing for NSF. Please assist the PWC by
visiting <a class="moz-txt-link-freetext"
href="http://geodynamics.org/cig/proposalsndocs/blogs/cig2-proposal">http://geodynamics.org/cig/proposalsndocs/blogs/cig2-proposal</a>
and downloading and reviewing both the proposal and the supplementary
material, and returning to that page to post your comments. CIG greatly
appreciates your feedback and thanks you in advance for your comments
and suggestions.<br>
<br>
<b>EC Selects Next Director</b><br>
<br>
* The Executive Committee is pleased to announce the appointment of
Prof. Louise Kellogg of University of California, Davis, as the next
Director of CIG. Louise was the most highly nominated candidate, and
brings considerable experience in computational geodynamics, software
development (through CIG and KeckCaves) and administration. We are
confident that Louise will provide the critical leadership that CIG
needs to take us through the proposal renewal and into the next
exciting phase of CIG development.<br>
<b><br>
Workshop Presentations/Tutorials Now Online</b><br>
<br>
* 2009 Workshop on Numerical Modeling of Crustal Deformation and
Earthquake Faulting, June 22-26, 2009, Golden, CO. The focus of this
gathering was on computational models addressing crustal deformation
with an emphasis on the seismic cycle across single and multiple
events. The workshop blended science talks on case studies from
particular faulting environments and on key rheological behavior with
discussions of current obstacles to crustal deformation modeling. The
workshop's presentations and tutorials are now available at
