Astrophysical Fluid Dynamics

The ERC AstroDyn Project at Nordita

Nordita ERC - European Research Council

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 Pencil Code, 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 allows the users easy updates and the possibility of sharing new and/or experimental developments with other users.
