Stiff ODE & Events Lab

Implicit solvers for stiff dynamics + optional event detection g(t,y)=0 — export Newton and step traces to Notebook.

ODE RIGHT-HAND SIDE f(t,y)
EVENT (optional) g(t,y)=0
Parameters
Sliders + constants for f(t,y) / g(t,y)
DEFINITIONS (one per line)
Use k=2 or k=0..30,1. Then reference k inside f / g. (t, y are reserved.)
t₀
y(t₀)
t₁
h (step)
max steps
METHOD
Newton tol
Newton max
Implicit methods require solving a nonlinear equation each step (Newton). If Newton fails, reduce h.
