SUNDIALS (SUite of Nonlinear and DIfferential/ALgebraic equation Solvers). SUNDIALS consists of the following four solvers:
- CVODE solves initial value problems for ordinary differential equation (ODE) systems.
- CVODES solves ODE systems and includes sensitivity analysis capabilities (forward and adjoint).
- IDA solves initial value problems for differential-algebraic equation (DAE) systems.
- KINSOL solves nonlinear algebraic systems.
