8The family of solvers referred to as SUNDIALS consists of the following solvers:
9 CVODE - for integration of ordinary differential equation systems (ODEs)
10 CVODE treats stiff and nonstiff ODE systems of the form
11 y' = f(t,y), y(t0) = y0
12 CVODES - for integration and sensitivity analysis of ODEs
13 CVODES treats stiff and nonstiff ODE systems of the form
14 y' = f(t,y,p), y(t0) = y0(p)
15 IDA - for integration of differential-algebraic equation systems (DAEs)
16 IDA treats DAE systems of the form
17 F(t,y,y') = 0, y(t0) = y0, y'(t0) = y0'
18 IDAS - for integration and sensitivity analysis of DAEs
19 IDAS treats DAE systems of the form
20 F(t,y,y',p) = 0, y(t0) = y0(p), y'(t0) = y0'(p)
21 KINSOL - for solution of nonlinear algebraic systems
22 KINSOL treats nonlinear systems of the form
23 F(u) = 0
24
25The various solvers of this family share many subordinate modules.
26For this reason, it is organized as a family, with a directory structure
27that exploits that sharing. Each individual solver includes documentation
28on installation, along with full usage documentation.
29
30Warning to users who receive more than one of these individual solvers
31at different times: The mixing of old and new versions SUNDIALS may fail.
32To avoid such failures, obtain all desired solvers at the same time.

34For installation directions see the file INSTALL_NOTES.

36For additional information on a particular solver, see the README file
37in the solver directory (e.g. src/cvode/README).
