Detailed Description

Abstract base class for time-dependent data at a level of refinement.

This is an abstract base class for data at the same level of refinement within a hierarchy of levels. The concrete class derived from AMRLevel is called a physics class. The domain of a level is a disjoint union of rectangles in a logically rectangular index space. Data is defined within this domain. There is also a problem domain, which may be larger, within which data can, in theory, be interpolated from some coarser level.

AMRLevel is intimately entangled with the AMR class. The AMR contains a collection of AMRLevel objects which represent a hierarchy of levels of refinement. The class AMR is responsible for calling the correct member functions of AMRLevel. The user is responsible for implementing the physics class, and might never call any AMRLevel functions described here.
