dome
The time evolution of a 3-D paraboloid dome of ice sitting on a flat bed. This is a very basic ice-sheet like test case that is simple and relatively fast to run. It confirms that the basic higher-order model physics are working, but it does not strenuously test the physics and boundary conditions.
