sundials: sundials (Equation Solvers) sundials: sundials: SUNDIALS was implemented with the goal of providing robust time sundials: integrators and nonlinear solvers that can easily be incorporated sundials: into existing simulation codes. The primary design goals were to sundials: require minimal information from the user, allow users to easily sundials: supply their own data structures underneath the solvers, and allow sundials: for easy incorporation of user-supplied linear solvers and sundials: preconditioners. sundials: sundials:
