Numerical benchmarks for spherical convection, dynamos and forced flow

Click on the links to retrieve the definitions.

1) Spherical shell dynamo with pseudo vacuum magnetic boundary conditions

This dynamo is a solution documented first by Harder & Hansen (GJI, 2005).
Since the boundary conditions are local, this benchmark is useful for non-spectral codes (e.g. finite volume, finite element, spectral element etc).
Computations have been carried out by Andrey Sheyko.

2) Whole sphere dynamo *UPDATED 1/10/12*  

Two benchmarks are available in a whole sphere with internal heating:
a) Non-magnetic convection
b) A dynamo that is purely oscillatory  (boundary conditions on B are the usual insulating type)
* Note two small amendments to the initial conditions were made mid-November, to speed convergence*
Computations have been carried out by Philippe Marti.

3) Whole sphere boundary driven flow  *UPDATED 12/9/12*

This is a purely hydrodynamical test.
Computations have been carried out by Nathanael Schaeffer
