### Stabilizing system behavior

A simulation that exhibits an oscillating behavior that
increases rapidly in amplitude points to unstable integration settings. When
this occurs, decrease the integration step size or switch to an integration
algorithm that yields more accurate results and produces less accumulated errors
over the course of the simulation, such as the adaptive Runge Kutta 5th order or
adaptive Bulirsh-Stoer integration algorithm.

For highly nonlinear systems or stiff systems, you should
use backward Euler.
