Detailed Description

template<size_t Dim, typename Registrars>
class AnalyticData< Dim, Registrars >

Provides analytic tensor data as a function of the spatial coordinates.

This abstract base class allows factory-creating derived classes from input-file options (see Registration). Both evolution systems and elliptic systems can use this abstract base class for their analytic data classes. Systems that have further requirements on their analytic data classes can add a subclass with additional virtual member functions.

This overload allows computing numeric derivatives using the Mesh and the inverse Jacobian, if necessary.
