SUNDIALS

SUNDIALS stands for SUite of Nonlinear and DIfferential/ALgebraic equation Solvers. It consists of the following six solvers:

• CVODE, for initial value problems for ODE systems

• CVODES, solves ODE systems and includes sensitivity analysis

• ARKODE, solves initial value ODE problems with Runge-Kutta methods

• IDA, solves initial value problems for differential-algebraic equation systems

• IDAS, solves differential-algebraic equation systems and includes sensitivity analysis

• KINSOL, solves nonlinear algebraic systems

AMReX provides interfaces to the SUNDIALS suite. For time integration, users can refer to the section Using SUNDIALS for more information. In addition, an example code demonstrating time integration with SUNDIALS can be found in the tutorials at, SUNDIALS and Time Integrators

For more information on SUNDIALS please see their readthedocs page.
