CVODE ODE solver interface

The abstract CVODE interface contains wrapper classes that make it easier to use the CVODE ODE solver package with C++ code in general, and SAMRAI in particular. There exist wrappers for Sundials vectors as well as the complete CVODE ODE solver. Apart from some minor preprocessor features, these interfaces are completely independent of the SAMRAI. The code which maps the vector interface included here to the SAMRAI framework can be found in the SAMRAI "Solvers" package.

These classes provide a C++ interface to the CVODE package, which is written in C. They are sufficiently generic that they may be used independently of the SAMRAI framework. The solver class wraps the CVODE data structures and function calls so that these items may be more easily used within a C++ program. Static member functions for the right hand side function evaluation, preconditioner setup and preconditioner solve are provided to link user-defined versions of these routines with CVODE and CVSpgmr. The "abstract function" class serves as the interface between the solver class and user-defined implementations of these routines.

CVODE/CVODE was developed in the Center for Applied Scientific Computing (CASC) at Lawrence Livermore National Laboratory (LLNL). For more information about CVODE and a complete description of the operations and data structures used by this class, see S.D. Cohen and A.C. Hindmarsh, "CVODE User Guide", UCRL-MA-118618, Lawrence Livermore National Laboratory, 1994.

Note: These classes assume that vectors based on the SundialsAbstractVector class are used.
