Model Description
ANMHD solves the three-dimensional system of magnetohydrodynamic equations in the anelastic approximation using a streamfunction formalism. The system is solved on a uniform Cartesian mesh. For a description of the numerical techniques, and the anelastic formalism in general, see

  • Fan Y., Zweibel, E. G., Linton, M. G., & Fisher, G. H., 1999, ApJ, 521, 460
  • Abbett, W. P., Fisher, G. H., & Fan, Y., 2001, ApJ, 546, 1194

ANMHD is the first code that the CCMC is offering that focuses specifically on numerical experiments rather than on developing modeling context to supplement data analysis.

Since there will be many lessons for us to learn about how best to offer this type of product to the community we plan to proceed methodically, and invite user feedback.

ANMHD will eventually be supported to run in three distinct modes, to study

  1. a twisted flux tube embedded in a non-rotating, convectively stable medium
  2. different convectively unstable solutions without an embedded flux tube
  3. the combination of modes 1 and 2, ie the evolution of twisted flux tubes embedded in a convectively unstable region.

For now we offer only mode 1, which is the least resource intensive. Once we have some experience with user requests, and a better sense of the potential user community and their specific interests, we will refine the overall model presentation and enable modes 2 and 3.

In mode 1, the model is restricted to modeling a twisted flux tube embedded in a non-rotating, convectively stable medium.

Model Input
For now, the Reynolds and Prandtl numbers are fixed, and the user is allowed to adjust the initial twist, field strength, and radius of the tube.

Model Output

Output Visualization

A selection of graphics will be delivered to the requestor on completion of the run. We do not yet have an interactive graphics capability for this code.

The initial users are encouraged to contact Peter MacNeice (see contact information below) for help in generating custom graphics for their runs.

An interactive graphics capability will be provided once we have feedback on its design from enough users.

Limitations and Caveats
For now we will offer only mode 1, which is the least resource intensive. Once we have some experience with user requests, and a better sense of the potential user community and their specific interests, we will refine the overall model presentation and enable modes 2 and 3.
