+ Multigrid: We are working on an
implementation of multigrid methods for
deal.II. While this is running on globally
refined grids, we are still having problems on locally
- refined grid. We hope to have them sorted out for the next
+ refined meshes. For those, multigrid is only applicable with
+ DG methods yet. We hope to have them sorted out for the next
major release.

- Linear solvers: - We already have the most common linear solvers, such as CG, - BiCGStab, or Minres. However, there are certainly more - proficient implementations of these solvers, but that would - need experts in this field which we certainly are not. It - would also be of interest to have linear solvers for more - complicated applications. -
- -- Faster linear algebra: The linear - algebra implementation in deal.II is quite - fast, at least compared to other C/C++ implementations. We - know that Fortran compilers can sometimes do a better job in - optimizing some algorithms. We therefore would like to - interface from C to Fortran for that purpose. -
- -- On the other hand, we have made some initial experiments with - interfacing to BLAS routines on SUN, but it turned out that - our own implementation of the routines we tried was faster - than the ones in the vendor BLAS. Nevertheless, interfacing - to LAPACK or other libraries implementing high level - algorithms would be interesting. -
-More output formats: It would be nice to have the possibility of writing output in
