From rene.gassmoeller at mailbox.org Wed Mar 1 10:28:32 2017 From: rene.gassmoeller at mailbox.org (Rene Gassmoeller) Date: Wed, 1 Mar 2017 11:28:32 -0700 Subject: [CIG-MC] ASPECT 1.5.0 released Message-ID: <35834483-f4fb-e1d6-b2e8-1b751d8abd1e@mailbox.org> We are pleased to announce the release of ASPECT 1.5.0. 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-MC] 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...

I extracted the compressed .tar file , but when I openned the folder there is any executable file that I could use to install the software. Can you help me with this issue? Thanks too much, Andrés Rodríguez -------------- next part -------------- An HTML attachment was scrubbed... URL:
