[ODE] New to ODE

Thanks for pointing out a couple of ideas.
To be honest I don't think I could manage either of those having little to
no ODE experience at the minute. The one thing I do have is time to learn
I've spoken to my lecturer and he suggested working with ODE to reduce
effects such as objects bouncing around long after the point at which they
would realistically have settled down. Like when you have a big pile of
objects. The problem I see is that the disable function and auto-disable
seem to have problems like this already under control, not a problem for
ODE, just for me :-)
Other than that I have been thinking about other modifications:
ODE calculates everything based on a time period since the last update
right? Perhaps I could update a single object many times, then move to
another and update several times. In esscence just updating more times per
object, rather than just once. Could improve speed?
I'm not sure if this is already in place but how about a value of
significance for objects. Objects with higher significance could be modelled
more accurately whereas insignificant objects are not so important. Disable
could be used to reduce calculations.
All of these ideas feel to me to be too shallow. I'm not even sure they
would require modifications of ODE code, rather just using the code and for
someone who is familiar with ODE it's probably somewhat trivial?
Thanks again for the reply,
