Dear DuMuXers,
we are happy to announce, that the 2.6 version of DuMuX is now available.
Hopefully you profit from the changes. We recommend to change to the
current version.
You can download the tarball from
http://www.dumux.org/download/dumux-2.6.0.tar.gz
Alternatively, and particularly if you want to develop within the DuMuX
module directory,
you can svn-checkout the release branch:
svn checkout --username=anonymous --password=''
svn://svn.iws.uni-stuttgart.de/DUMUX/dumux/branches/release-2.6dumux
Below you find the most important changes:
Differences Between DuMuX 2.5 and DuMuX 2.6
===================================================
- For the non-isothermal porous media models, the energy equation is
implemented in a more generic way for all models in
dumux/implicit/nonisothermal. In principle, any isothermal
porous media model can be enhanced with the energy equation. See
dumux/implicit/2p/2ppropert*.hh for details.
- The AMG backend is based directly on dune-istl now. No PDELab is required
anymore. The tests so far exhibit an improved robustness. Thanks to Markus
Blatt for the work.
- The multidomain models can now be used with the 2.3 release versions
of the
DUNE core modules and dune-multidomaingrid, and the 2.0 release versions
of dune-pdelab and dune-multidomain. See test/multidomain/README for
details.
- In the fully implicit mpnc model, a further specialization allows now to
describe two-phase flow with two energy equations.
- The free flow models now include the component enthalpy fluxes transported
by diffusion processes (h^k D grad x), which was not considered before.
- UMFPack is a new direct linear solver and can be use as a drop-in
replacement for SuperLU. Some users claim a speed-up up to a factor of
seven. We know cases where it was 10% slower, so please measure for your
problems.
Have a lot of fun and best regards,
Natalie
