The code is built on modern numerical methods, incorporating adaptive mesh refinement and advanced linear and nonlinear solvers. This webinar highlights ASPECT’s new features, such as a graphical user interface for the creation and modification of input files, an overhaul of the solver for coupled magma/mantle dynamics, a new system for combining boundary and initial conditions, operator splitting methods to decouple fast reactions from advection, a material model for grain size evolution, a Newton solver and many other improvements.

Instructions on booking accommodations can be found here: https://meeting2018.cgu-ugc.ca/accommodation/ At this time, uptake of our economy rooms at the Radisson and Sheraton Four Points are fully taken up. There remains, however, a still quite large number of rooms available at the Marriott Fallsview, which is extremely close to the conference centre, still a great deal ($100-$150 cheaper per night than is currently available on discount travel websites) and for which the conference will be held financially responsible if too many rooms remain unbooked. Thus, taking advantage of these rates is not only good for your research program's pocketbook, but also for the non-profit societies you belong to. We very much look forward to seeing you in Niagara Falls in about a month!

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.geodynamics.org/ and the release is available from         https://github.com/geodynamics/aspect/releases/tag/v2.0.0 This release includes the following changes: - New: Newton solver and defect correction Picard iterations for nonlinear   problems (for the Stokes system) - Melt solver: Overhaul leading to improved performance and stability, better   integration with other plugins - New: Material model with grain size evolution - New: Boundary temperature plugin with evolving core-mantle boundary   temperature based on the heat flux through the core-mantle boundary - New: ASPECT can now compute the geoid in 3D spherical shell geometry - New: Operator splitting for reactions between compositional fields - New: Added a PREM gravity profile - Improved: Significantly reduced memory consumption in models that use many   compositional fields - Improved: A large number of performance improvements for preconditioners,   assembly, seismic tomography initial conditions, and lateral averaging - Improved: More flexibility for boundary and initial conditions, different   plugins can be combined - Improved: The dynamic topography postprocessor now uses the consistent   boundary flux method for computing surface stresses, which is significantly   more accurate - New: Additional RHS force terms in the Stokes system can be added - New particle interpolators: nearest neighbor, bilinear least squares,   harmonic average - New: Graphical user interface for the creation and modification of input   parameter files - Many other fixes and small improvements. - Rework: Updated parameter and section names to make them more consistent and   easier to understand. A script for updating parameter and source files is   provided with the release. A complete list of changes can be found at   https://aspect.geodynamics.org/doc/doxygen/changes_between_1_85_80_and_2_80_80.html Information about how to cite ASPECT can be found at   https://aspect.geodynamics.org/cite.html and   https://geodynamics.org/cig/abc/?software=aspect&version=2.0.0 Wolfgang Bangerth, Juliane Dannberg, Rene Gassmoeller, Timo Heister, Jacqueline Austermann, Menno Fraters, Anne Glerum, John Naliboff, and many other contributors. -- Rene Gassmoeller https://gassmoeller.github.io/ From ljhwang at ucdavis.edu Mon May 14 09:59:53 2018 From: ljhwang at ucdavis.edu (Lorraine Hwang) Date: Mon, 14 May 2018 09:59:53 -0700 Subject: [CIG-LONG] 2018 CGU CIG Joint Meeting - Hotel deadline extended Message-ID: 2018 CGU CIG Joint Meeting - June 10-14, Niagara Falls Rooms are still available at the meeting rate for the Marriott Fallsview Hotel for the upcoming 2018 CGU CIG Joint Meeting in Niagara Falls, Canada.
