After lots of developing, debugging, and documenting, we have finally
released Aspect version 0.1. Aspect -- short for Advanced Solver for
Problems in Earth's ConvecTion -- is a code intended as a simulator for
thermally driven convection, for example in the earth mantle. Its design
goals are:
- Use of modern numerical methods, such as (i) higher order finite
elements, (ii) adaptivity, (iii) efficient and scalable solvers
and preconditioners, (iv) parallelization to hundreds of processors
and beyond.
- Reuse of widely used, well tested library to provide the underlying
numerical framework; specifically, Aspect builds on deal.II, Trilinos
and p4est.
- Extensibility: It should be easy to replace the geometry model or the
rheology, as well as a host of other things that characterize a
problem under consideration.
The Aspect homepage is located at

where you can also find links to the tar-file for download as well as to
the manual. We look forward to your feedback!

PS: This being version 0.1, you may wonder what's still missing. By and
large, we are quite confident in the correctness of the code as well as
with the performance of it. Some of the things that didn't make it into
this first release are:
- Some sections in the manual aren't written yet.
- There currently aren't enough cookbook examples.
- The current algorithm is using an operator splitting technique to deal
with nonlinear material laws. This will ultimately be rewritten to use
a Newton-type method.
We hope to get to these points in the near future.
