We should book the room for the MAPDES meetings *next* term. The calendar says we picked 2pm on Fridays. Christian finds Fridays very hard. How about 2pm on Mondays instead? Paul

Block preconditioning for Stokes-like problems with DOLFIN
by Florian Rathgeber 08 Dec '13

08 Dec '13

You may have seen this already: Garth has published some code using PETSc FieldSplit preconditioners for block preconditioning of Stokes-like problems with DOLFIN (C++ interface only) [1]. This is code for magma dynamics problems from a paper by Sander Rhebergen, Garth et. al which is published on arXiv [2]. You should join the FEniCS community on G+ [3] if you haven't already. Florian [1]: https://bitbucket.org/magma-dynamics/preconditioning [2]: http://arxiv.org/abs/1311.6372 [3]: https://plus.google.com/u/0/communities/105550716956576029273

Hi Rod, That might be tricky. I had anticipated standing at a whiteboard and winging it, and I am not aware of us having a room with the right gear to webcast that, although if someone wants to prove me wrong I'm all ears.

Hi All, Today we're going to look at chapter 1 of Brenner and Scott, and particularly up to page 36, so you may choose to bring along a printout if you wish to follow along.
