How about using Runge-Kutta 4? 6 Years, 3 Months ago Karma: 0  
How about using Runge-Kutta 4 as an integration method? Sphinx SD appears to use Euler's method. This is unsatisfactory for undamped oscillatory systems. Euler's method causes the bounds of the oscillation to keep increasing. The only way to manage this is to use a miniscule value for DT.
