# SUNDIALS [SUNDIALS](https://computing.llnl.gov/projects/sundials) is an open-source suite of solvers for ordinary differential equations, differential-algebraic equations, and nonlinear algebraic systems, developed at Lawrence Livermore National Laboratory. It provides adaptive time integration methods and Newton-based nonlinear solvers for serial and parallel computing environments. ## Examples ```{toctree} :maxdepth: 1 Poisson (KINSOL) Stiff ODE (CVODE) ```
