[aspect-devel] ASPECT 2.0.1 released

[Rene Gassmoeller]

We are pleased to announce the release of ASPECT 2.0.1. 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/v2.0.1

This release is a bugfix release for 2.0.0 and includes the following fixes:
- Fixed: The 'compositional heating' heating plugin had a parameter
   'Use compositional field for heat production averaging' that was used
   inconsistently with its description. Its first entry did not correspond
   to the background field, but to the first compositional field, and the
   last value was ignored. This is fixed now, the first entry is used for
   the background field, and all following values determine whether to 
include
   the corresponding compositional fields.
- Fixed: The 'depth dependent' material model did not properly initialize
   the material model it uses as a base model. This caused crashes if the
   base model requires an initialization (such as the 'steinberger' material
   model). This is fixed now by properly initializing the base model.
- Fixed: The advection assembler for DG elements was not thread-safe,
   which led to wrong results or crashes if a discontinuous temperature
   or composition discretization was combined with multithreading.
- Disabled: The particle functionality was not tested when combined with a
   free surface boundary, and this combination is currently not 
supported. This
   limitation is now made clear by failing for such setups with a 
descriptive
   error message.
