The ODE Solvers module provides time integration functions for explicit, stiff, and implicit differential equation workflows in Nelson.

It includes solver entry points, delay and boundary value problem wrappers, option handling, interpolation, solution extension, event detection, and object-oriented problem definitions.

When the optional SUNDIALS backend is built, the object workflow can also select CVODES and IDAS solver values.

The module is designed for numerical experiments, simulations, and teaching examples that need compact solver setup and reproducible result objects.

Tutorial pages cover solver choice, events, tolerances, mass matrices, implicit equations, delay equations, boundary value problems, interpolation, extension, object workflows, and complex states.
