The ARKode Solver

The ARKode solver library provides an adaptive-step time integration package for stiff, nonstiff and mixed systems of ordinary differential equations (ODEs) given in linearly-implicit form,

\[M \dot{y} = f_E(t,y) + f_I(t,y).\]

Here,

Either of the operators \(f_E\) or \(f_I\) may be disabled, allowing for fully explicit, fully implicit, or combination implicit-explicit (IMEX) time integration.

ARKode is a component of the SUNDIALS suite of nonlinear and differential/algebraic equation solvers.

ARKode is written in C, with C++ and Fortran interfaces.
