ASPECT is the Advanced Solver for Problems in Earth's ConvecTion. It uses modern numerical methods such as adaptive mesh refinement, multigrid, and a modular software design to provide a fast, flexible, and extensible mantle convection solver. ASPECT is available from https://aspect.dealii.org/ and the release is available from https://github.com/geodynamics/aspect/releases/tag/v1.5.0 This release includes the following changes: - New: Choice between different formulations for the governing equations including Boussinesq and anelastic liquid approximation. - New: Melt transport (two-phase flow). - Particles: new generators, ghost exchange, performance improvements, interpolation to fields. - New: Nondimensional material model for incompressible (using the Boussinesq approximation) and compressible computations (with ALA or TALA) for nondimensionalized problems. This can be used for benchmark problems like Blankenbach, King, etc.. - New: Optional DG method for temperature/composition. - Adiabatic conditions: rework, now includes a reference density profile. - Free surface: overhaul. - New cookbooks: continental extension, finite strain, BurnMan interface, active tracers. - New benchmarks: TanGurnis, Blankenbach, King. - New: viscoplastic material model. - Material model interface cleanup. - Assembly performance improvements. - New: memory statistics postprocessor. - New: initial topography plugins. - Many other fixes and small improvements. A complete list of changes can be found at https://aspect.dealii.org/doc/doxygen/changes_between_1_84_80_and_1_85_80.html and the release is also available from https://github.com/geodynamics/aspect/releases/tag/v1.5.0 Wolfgang Bangerth, Juliane Dannberg, Rene Gassmoeller, Timo Heister, and many other contributors. -- Rene Gassmoeller http://www.math.colostate.edu/~gassmoel/ From ljhwang at ucdavis.edu Sun Mar 5 10:41:35 2017 From: ljhwang at ucdavis.edu (Lorraine Hwang) Date: Sun, 5 Mar 2017 10:41:35 -0800 Subject: [CIG-ALL] This Week's Webinar and Summer Workshops Message-ID: <18507CF1-C820-4296-8F6B-80D38A4A0CD8@ucdavis.edu> Don’t miss the following CIG events.

The gravitational potential is governed by Poisson’s equation inside the Earth and by Laplace’s equation in the rest of space. The infinite domain and large-scale nature of the problem poses difficult challenges for numerical simulations in 3D Earth models. In order to tackle these challenges, we introduce a spectral-infinite-element method by combining the spectral-element method with the mapped infinite-element method. Spectral elements are used to represent internal fields, and infinite elements represent the external gravitational field. Infinite elements naturally couple with spectral elements, thereby avoiding an iterative procedure which is necessary if the Poisson/Laplace equation has to be solved independently. Potential applications of new method include long-period seismic wave propagation, as well as quasistatic problems, such as post-earthquake relaxation and glacial isostatic adjustment. ——————————————————————————————————————————————————— REGISTRATION DEADLINES 2017 ASPECT Hackathon May 6-17 Blue Ridge, Georgia https://geodynamics.org/cig/events/calendar/2017-aspect-hack/?eID=1300 Registration Closes: March 31, 2017 Notification of Acceptance Begins: April 1, 2017 2017 Crustal Deformation Modeling Workshop June 26-30 Golden, Colorado https://geodynamics.org/cig/events/calendar/2017-cdm-workshop/?eID=1292 Registration Closes: May 15, 2017 Notification of travel support begins: April 1, 2017 *** Registration is first come first serve and limited to 60 participants -------------- next part -------------- An HTML attachment was scrubbed...

Supporting the development of spatial thinking in a science curriculum requires an interdisciplinary effort that combines knowledge of the disciplinary science with education and psychology expertise. The network is designed to create a "trading zone" where theory and practice converge so that research on education and cognitive psychology can be influenced by disciplinary geoscience content, and vice versa, to result in new designs for teaching tools and new insights into the working of the human mind-brain. The network seeks to expand our fundamental understanding of the science of learning by characterizing the different types of spatial reasoning required for the practice of a complex spatial science, and to develop new supports for spatial learning challenges that have been barriers for student learning. Tools developed in this project are designed to allow students to self-correct conceptual errors in their understanding of scientific concepts. The practice of the network will be illustrated with two examples of the application of: 1) Spatial feedback, which is feedback in the form of a spatial error that allows the mind-brain to guide learning, And 2) Spatial accommodation, which is the constructing and reconstructing of mental models to accurately incorporate spatial information to improve inaccurate mental models from spatial feedback. Geoscientists are required to make sense of information using multiple spatial frames of reference. A complex example may be deciphering the sequence of tectonic events from a complex outcrop. Students make predictable errors from a simple frame of reference problem; when asked to predict where the next volcanic crater will form based on plate motion, students commonly respond with an incorrect answer that is opposite of the correct answer. Similarly, geoscientists must make sense of some complex spatial patterns by visualizing non-rigid transformations. When students are asked to predict the direction and magnitude of motion as reported by GPS around an active fault they make systematic errors, as well. In the second installment of the IRIS webinar series on Geoscience Education Research, researchers will present a model and suggestions for developing an interdisciplinary network, examples of spatial problems facing students in your classes, and suggestions for classroom practice that can help students overcome spatial challenges. ---- Learn more about the presenters, their collaboration, and the Geoscience Educational Transdisciplinary Spatial Learning Network here: http://serc.carleton.edu/getspatial/index.html After registering, you will receive a confirmation email containing information about joining the webinar.

This release provides a few new minor features and bugfixes. You can download the source code and binaries from http://geodynamics.org/cig/software/pylith Detailed installation instructions for the binary packages are in the User Manual with detailed building instructions for a few platforms in the INSTALL file bundled with the PyLith Installer utility. We also offer a Docker image (https://wiki.geodynamics.org/software:pylith:docker) for running PyLith within a portable, virtual Linux environment. ====================================================================== MIGRATING FROM VERSION 2.1 TO 2.2 ====================================================================== No changes are needed to parameter or other input files. The default format for pylithinfo output is now JSON. ====================================================================== RELEASE NOTES ====================================================================== * Added a browser-based parameter viewer for interactive viewing of all PyLith parameters and version information. See Section 4.10 PyLith Parameter Viewer of the PyLith user manual. * Adjusted packaging of the binary distributions so that they can be used to extend PyLith and/or integrate other code with PyLith. * Converted the user manual from Lyx to LaTeX and added syntax highlighting of parameter and spatial database files. Fixed several typos. * Fixed bug that sometimes resulted in an inconsistent fault orientation when running in parallel. The bug appears to have been introduced in v2.0. * Fixed two bugs in output of solution at points that sometimes happened in parallel simulations. The errors include: - The order of the station names does not match the order of the points. The point data is written in parallel by process order, so the points for process 0 are written first, then those for process 1, etc. This often results in reordering of the points. The station names were written in the original order. - The output values for some points are incorrect. The wrong cells were being used in the interpolation. * Updated PETSc to v3.7.5. See CHANGES in the top-level source directory for a list of changes for each prior release.
