Astrophysical turbulence and dynamo action
AbstractSupport for large-scale computing is being requested. In connection with my new VR breakthrough research grant on the "Formation of active regions in the Sun", in addition to a regular VR project grant on "Turbulent dynamo simulation in a spherical shell segment", a number of people are working on projects connected with this application. In addition to dynamos, we are also working on sunspots and helioseismology, and plan to make predictions about the magnetic influence of the so-called surface mode (or f-mode). Many of us use the Pencil Code (http://pencil-code.googlecode.com), which is a sixth order finite difference code with a third order time stepping scheme. The code uses MPI and is running on a range of different platforms around the world and is designed to work on large clusters. It is in the public domain and developed by an increasing number of project participants (currently 92 people of which 10 have project owner status). In the last year alone, since October 2012, Swedish computing resources are acknowledged in the 14 refereed papers of our last activity report; see http://www.nordita.org/~brandenb/AstroDyn/progress/computing/report13.pdf. This work in connected with two PhD theses to be continued in 2013 and three PhD thesis that will be completed later this year. |
