[aspect-devel] Input parameters for the compressible mantle convection?

[Juliane Dannberg]

Hi Nan,

if you go to the benchmarks folder, there's the directory "tangurnis" 
that contains input files for the different approximations tested in the 
benchmark of Tan, Gurnis '07 (which is compressible).

For a time-dependent problem, we're still working on the King '10 
benchmark cases. Timo has some preliminary results on one of his 
branches (https://github.com/tjhei/aspect/tree/density_approximations); 
but note that this branch also contains changes to the code itself, so 
you will only be able to compare results if you checkout, compile and 
run the models with his branch.

Best,
Juliane
