Using MRIStep for C and C++ ApplicationsΒΆ

This chapter is concerned with the use of the MRIStep time-stepping module for the solution of two-rate initial value problems (IVPs) in a C or C++ language setting. The following sections discuss the header files and the layout of the user’s main program, and provide descriptions of the MRIStep user-callable functions and user-supplied functions.

The example programs described in the companion document [R2018] may be helpful. Those codes may be used as templates for new codes and are included in the ARKode package examples subdirectory.

MRIStep uses the input and output constants from the shared ARKode infrastructure. These are defined as needed in this chapter, but for convenience the full list is provided separately in the section Appendix: ARKode Constants.

The relevant information on using MRIStep’s C and C++ interfaces is detailed in the following sub-sections.
