Training Sessions for Computational Software in Tectonics and Geophysics
Boise Centre on the Grove, Boise ID
May 12, 2009
8 a.m. to 3 p.m.

Data from the US Array and PBO components of EarthScope allow an  
extraordinary opportunity to better understand Earth structure and  
dynamics. An important component of interpreting such data is the use  
of computational methodologies to simulate tectonic processes.  In  
this training session, the Computational Infrastructure for  
Geodynamics (CIG), an NSF center, will focus on training of new users  
in the use of software that can be used for the interpretation and  
modeling of EarthScope data. During the session, participants will be  
given background theory, an overview of the codes including their  
strengths and weaknesses for solving geodynamic problems, and  
instruction on downloading and running these codes (including running  
them on the NSF TeraGrid), and post-processing (visualizing) the  
CIG will sponsor two one-day training sessions. Some financial  
support is available for graduate students and post-docs who  
participate in this training session. For additional information see


1. Tectonic Models.

Training will be provided in the use of the PyLith and Gale software  
packages. PyLith is a finite element code for the solution of dynamic  
and quasi-static tectonic deformation problems in one, two, or three  
dimensions. Gale is a 2D/3D parallel code that solves problems in  
orogenesis, rifting, and subduction with a variety of boundary  
conditions, including free surfaces and coupling to surface erosion  
models.  As time permits, the workshop will also cover how to  
implement new rheologies and custom surface processes in Gale.


PyLith: Brad Aagaard (USGS), Charles Williams (GNS Science)

Gale: Walter Landry (CIG)

2. Large-Scale Earth Models.

Training will be provided in the use of the SPECFEM and CitcomS  
software packages for modeling structure and dynamics at regional to  
global scales. SPECFEM3D_GLOBE simulates global and regional  
(continental-scale) seismic wave propagation, and handles the effects  
of lateral variations in compressional-wave speed, shear-wave speed,  
density, 3D crustal thickness, ellipticity, topography and  
bathymetry, the oceans, rotation, and self-gravitation. CitcomS is a  
finite-element code designed to solve convection problems relevant to  
Earth's mantle and plate tectonics, which can handle a variety of  
temperature, stress, pressure, and compositional rheologies, thermo- 
chemical convection, and plate tectonic boundary conditions.


CitcomS: Eh Tan (CIG)

SPECFEM: Kasper van Wijk (Boise State), Leif Strand (CIG)
