Dear DuMuX community,
We are happy to announce today's alpha release of DuMuX 3.0!
DuMuX 3.0 will offer increased flexibility through a less
inter-dependent class design and a more modular structure. These modules
can easily be accessed and used as the formerly predetermined simulation
path by means of the Dumux::start() routine has been abandoned in favor
of a user-defined main file. This allows rapid and transparent adaption
of the program flow to individual needs. Furthermore, all structures
required for the assembly of the global system matrix and residual
calculations have been abstracted such that new spatial discretization
schemes can be integrated more easily by providing adequate
specializations.
Further Highlights:
- considerably faster Jacobian assembly
- staggered grid implementation for free-flow models
- multi-point flux approximation scheme for all porous medium flow models
- improved parameter handling
New capabilities in the near future:
- mixeddimension module for coupled simulations of lower-dimensional
grids embedded in a fully-dimensional grid
- mimetic finite differences and non-linear two-point flux approximation
for all porous medium flow models
Things we lost for now, but will be integrated again soon:
- geomechanics module (will return without dependency on dune-pdelab)
- multidomain models (will return without dependency on dune-pdelab and
dune-multidomain)
- box 2pdfm model
- partial Jacobian reassembly
Things we lost on the way:
- Navier-Stokes model using the box scheme
- Jacobian matrix recycling
This is an alpha release, so please don't expect that things run
smoothly already. Moreover, the master can still be subject to immediate
interface changes. Nevertheless, we would be very happy if you already
could take a look at 3.0 and provide us with your valuable feedback! To
get the release, perform a
git checkout tags/3.0.0-alpha
in your Dumux Git repo.
We are looking forward to releasing DuMuX 3.0 next spring!
On the behalf of all developers, I wish you all a merry christmas, a
happy new year and all the best using DuMuX 3.0! Please let us know if
you encounter any problems.
Dennis
