Astrophysical Dynamo Project at Nordita
The European Research Council decided in 2008 to fund a concentrated
5-year effort at Nordita
in Stockholm to improve our understanding of astrophysical dynamos.
This work couples large-scale numerical simulations with numerically
guided analytical approaches.
An ultimate goal is to have a physically consistent model of the solar dynamo.
Simulations, on the one hand, still lack some potentially important
properties (tachocline, near-surface shear layer, ability to shed
small-scale magnetic helicity), while analytic approaches (including
mean-field theory) are still being developed to explain and reproduce
more successfully some of the systematic behaviors seen in simulations.
One of the default research tool is the
which is a public domain code initiated at Nordita and used for solving
partial differential equations on massively parallel computers.
It is now hosted by Github.
Its maintenance through a remote versioning system (SVN) allows the users
easy updates and the possibility of sharing new and/or experimental
developments with other users.
