Announcement for 1.2 (January 25rd, 2015)
63+
-----------------------------------------
64+
We are pleased to announce the release of ASPECT 1.2. ASPECT is the Advanced
65+
Solver for Problems in Earth's ConvecTion. It uses modern numerical methods such
66+
as adaptive mesh refinement, multigrid, and a modular software design to
67+
provide a fast, flexible and extensible mantle convection solver. ASPECT is
68+
available from
69+
70+
http://aspect.dealii.org/
71+
72+
This release includes the following changes:
73+
- methods to have truly concentric shells without distorted cells
74+
- linear solver improvements which give up to 2x speedup in some cases
75+
- boundary names like "top" instead of numbers are now supported in input files
76+
- new example: free surface computation with a crust as a stagnant lid
77+
- new benchmarks: Davies et al. and Burstedde et al.
78+
- new initial condition: S40RTS perturbation based on shear wave data
79+
- fixes to minimum/maximum refinement plugins
80+
- better error messages when linear solvers fail
81+
- many other fixes and small improvements (direct solver, file output,
82+
checkpointing, etc.)
