All, over the last few months, the multigrid implementation has seen significant rewrites, with much of the work done by Baerbel Janssen. The goal -- now achieved -- was to finally fully support multigrid also for continuous finite elements on adaptively refined meshes (uniformly refined meshes and discontinuous elements have worked for a long time).
As part of this process, step-16 has been rewritten and now solves the same problem step-6 solves, just with a multigrid solver. Take a look at http://www.dealii.org/developer/doxygen/deal.II/step_16.html There is still work to be done. In particular, there are still a few things that don't seem to work for vector-valued problems (along with a few things where I think we don't quite understand the correct mathematical formulation). But we're working on that :-) Cheers W. -- ------------------------------------------------------------------------- Wolfgang Bangerth email: [email protected] www: http://www.math.tamu.edu/~bangerth/ _______________________________________________ dealii mailing list http://poisson.dealii.org/mailman/listinfo/dealii
