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

"Introduction to the spectral-infinite-element method"
~ by Hom Nath Gharti and Jeroen Tromp, Princeton University
The governing equations for the elastic-gravitational deformation of
an Earth model involve a perturbed gravitational potential. 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.

Subject: [CIG-MC] Question about Installation
Message-ID:
Greetings CIG developers, I am very interested in using the Citcoms code, however, I am a windows user and at the moment I dont know how to do to installed it. 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
