Hello,
There is not a specific transitioning guide I can point you to other than the recent changes section in the introduction of the ARKode user guide. Additionally, you may find the “USING ARKSTEP FOR C AND C++ APPLICATIONS” section useful.
In SUNDIALS 4, ARKode was modularized into three time-stepping modules: ARKStep, ERKStep, and MRIStep. The ARKStep module is the Additive Runge-Kutta time-stepping module and provides all of the functionality available in ARKode in SUNDIALS 3. In fact, most of the methods can still be called just by changing the “ARKode” in the function name to “ARKStep”, e.g. ARKodeSStolerances
--> ARKStepSStolerances
.
To use the ARKStep module, you'll need to include the header file include/arkode/arkode_arkstep.h
. This will resolve most of the errors in that output. Additionally, The ARK_S_MAX
macro is no longer needed (or provided) - see the ARKodeButcherTable
structure and associated functions in the user guide (they are defined in the include/arkode/arkode_butcher.h
header file).
