In sundialr: An Interface to 'SUNDIALS' Ordinary Differential Equation (ODE) Solvers

CVODES

Version 5.2.0 (Mar 2020)

Alan C. Hindmarsh and Radu Serban Center for Applied Scientific Computing, LLNL

CVODES is a package for the solution of stiff and nonstiff ordinary differential equation (ODE) systems (initial value problem) given in explicit form

dy/dt = f(t,y,p), y(t0) = y0(p)

with sensitivity analysis capabilities (both forward and adjoint modes). CVODES provides a choice of two variable-order, variable-coefficient multistep methods, Adams-Moulton methods for non-stiff problems or BDF (Backward Differentiation Formula) methods in fixed-leading-coefficient form for stiff problems.

CVODES is part of the SUNDIALS Suite of Nonlinear and Differential/Algebraic equation Solvers which consists of ARKode, CVODE, CVODES, IDA, IDAS and KINSOL. It is written in ANSI standard C and can be used in a variety of computing environments including serial, shared memory, distributed memory, and accelerator-based (e.g., GPU) systems. This flexibility is obtained from a modular design that leverages the shared vector, matrix, linear solver, and nonlinear solver APIs used across SUNDIALS packages.
