Cigma 1.0, ConMan 2.0, and SNAC ?.? released; Gale 1.3.1 and PyLith 1.3.1 bug-fixes available; CIG solicits feedback, encourages proposals; CIG Business Meeting on Dec 16; Geo-Math workshop presentations and posters online; new EC and SSC members elected.

CIG Software Releases

Cigma 1.0 - The CIG Model Analyzer (Cigma) is a tool for standardizing error analysis and benchmarking of geodynamics modeling codes. Highlights of this 0.9.1 release include faster comparisons between two finite element solutions, the ability to specify an exact solution at specific points, and the ability to read Cigma datasets from VTK input files. See Cigma for source code and manual.
Conman 2.0 - ConMan is a vectorized finite element program for the solution of the equations of incompressible, infinite-Prandtl number convection in two dimensions, originally written by Arthur Raefsky, Scott King, and Brad Hager. See ConMan for source code and manual.
SNAC ?.? - SNAC is --what?--. See SNAC for source code and manual.

Software Bug Fixes

Gale 1.3.1 - Gale is a 2D/3D code that solves problems related to orogenesis, rifting, and subduction with coupling to surface erosion models. This latest release [does what?]. Gale is a joint effort between CIG, Victorian Partnership for Advanced Computing (VPAC), and Monash University. See Gale for binaries, source code, and manual.
PyLith 1.3.1- PyLith is a finite element code for the solution of visco-elastic/plastic deformation that was designed for lithospheric modeling problems. This bug-fix [does what?]. See PyLith for source code, binaries, and manual.

CIG encourages member proposals to NSF and solicits feedback on CIG-II

CIG recently sent out a letter detailing plans for continuing its activities beyond the end of current funding and encouraging members of the community to collaborate with computational scientists and seek funding from some relatively new NSF programs. We also want your feedback; read the Open Letter to the Community and click the Comments button at the end to provide your input.

Upcoming Meetings

CIG Business Meeting, Tuesday, December 16 (during AGU), 6-8:30 p.m., Parc 55 Hotel, Sienna Room (3rd Floor), San Francisco. You are invited to this public forum for members of the Geosciences community to discuss the future development of CIG. Expect the main focus to be on plans for the future, including proposals for CIG-II.

Presentations and Posters from GeoMath08 Workshop Online

CIG Workshop on Mathematical and Computational Issues in the Solid Earth Geosciences, Sept. 15-17, 2008, Santa Fe, NM. This CIG workshop brought together solid-earth geoscientists, mathematicians, computational and computer scientists to focus on specific issues arising from a range of solid-Earth dynamics problems that have proven both difficult and critical for progress in studying and modeling the dynamics of the planet. The Workshop Agenda now includes links to all the presentations and posters given at the workshop.

EC and SSC Committee Updates

New EC and SSC Members - We are pleased to announce that the following people will be CIG's new officers filling 3-year terms:

EC: Bill Appelbe (VPAC)
SSC: Luc Lavier (U Texas at Austin), Andy Freed (Purdue), and Wolfgang Bangerth (reelected)

Thanks to all who agreed to stand for election, and thanks also to the outgoing members of the EC and SSC for their service to CIG: Brad Hager for two years on the EC. most recently serving as vice-chair; Brad Aagaard for three years on the SSC, this last year as its chairman; and Shijie Zhong who also served three years on the SSC. We also appreciate the efforts of the Nominating Committee, Brad Hager, Laurent Montesi, and Shijie Zhong, for their fine work putting together the slate of candidates.
