The last time I used spice, back when the pyramids

were young, it was not particularly well optimized

for this.

and I think SCEPTRE is older!!!!

If all you care about is a simple harmonic oscillator,

one excellent way to guarantee good long-term behavior

is to use a /symplectic/ integrator. The simplest

versions of this are exceedingly simple, and can be

expressed in a spreadsheet in less time than it takes

to tell about it.

Fancy symplectic integrators are very fancy indeed,

and very very accurate, but this is probably more

than you need at the moment.

For the next level of detail on all this, see

Excellent explanation, I was reading about symplectic integrators, but

your page is great!.

Thank you very much.
