SUNDIALS is a family of software packages implemented with the goal of providing robust time integrators and nonlinear solvers that can easily be incorporated into existing simulation codes. The primary design goals are to require minimal information from the user, allow users to easily supply their own data structures underneath the packages, and allow for easy incorporation of user-supplied linear solvers and preconditioners. The various packages share many subordinate modules and are organized as a family with a directory structure that exploits sharing common functionality.
The SUNDIALS suite consists of the following packages:
ARKODE - for integration of stiff and nonstiff ordinary differential equation systems (ODEs) of the form
M y' = fe(t,y) + fi(t,y), y(t0) = y0
CVODE - for integration of stiff and nonstiff ordinary differential equation systems (ODEs) of the form
y' = f(t,y), y(t0) = y0
CVODES - for integration and sensitivity analysis (forward and adjoint) of ordinary differential equation systems (ODEs) of the form
y' = f(t,y,p), y(t0) = y0(p)
IDA - for integration of differential-algebraic equation systems (DAEs) of the form
F(t,y,y') = 0, y(t0) = y0, y'(t0) = y0'
IDAS - for integration and sensitivity analysis (forward and adjoint) of differential-algebraic equation systems (DAEs) of the form
F(t,y,y',p) = 0, y(t0) = y0(p), y'(t0) = y0'(p)
KINSOL - for solution of nonlinear algebraic systems of the form
F(u) = 0
For installation directions see the INSTALL_GUIDE.pdf file or the installation chapter in any of the package user guides.
Warning to users who receive more than one of the individual packages at different times: Mixing old and new versions of SUNDIALS may fail. To avoid such failures, obtain all desired package at the same time.
Full user guides for SUNDIALS packages are provided in the doc directory along with documentation for example programs.
A list of Frequently Asked Questions on build and installation procedures as well as common usage issues is available on the SUNDIALS FAQ.
For dealing with systems with unphysical solutions or discontinuities see the SUNDIALS usage notes.
If you have a question not covered in the FAQ or usage notes, please submit your question to the SUNDIALS mailing list.
