CVODE is a solver for stiff and nonstiff ODE systems using variable-order, variable-step multistep methods: Adams-Moulton (nonstiff) and BDF (stiff). Provenance chain: 1. Lawrence Livermore National Security — original CVODE solver (C, 2002) Part of the SUNDIALS suite. Developed under U.S. Department of Energy Contract DE-AC52-07NA27344.
